restriction endonuclease subunit S [Fructilactobacillus florum]

Protein Classification

restriction endonuclease subunit S domain-containing protein( domain architecture ID 1000239)

type I restriction-modification system specificity (S) subunit (HsdS) dictates DNA sequence specificity; it consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs; each TRD binds to different specific sequences in the DNA

Type I restriction-modification system specificity (S) subunit Target Recognition ...
9-181 8.12e-19

Type I restriction-modification system specificity (S) subunit Target Recognition Domain-ConseRved domain (TRD-CR) and similar domains; The restriction-modification (RM) system S subunit generally consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs. The TRDs each bind to different specific sequences in the DNA. RM systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host genome is protected from cleavage by methylation of specific nucleotides in the target sites. In type I systems, both restriction and modification activities are present in one heteromeric enzyme complex composed of one DNA specificity (S) subunit (this family), two modification (M) subunits and two restriction (R) subunits. This superfamily represents a single TRD-CR unit; in addition to type I TRD-CR units, it includes RMtype1_S_TRD-CR_like domains of various putative Helicobacter type II restriction enzymes and methyltransferases, such as Hci611ORFHP and HfeORF12890P, as well as TRD-CR-like sequence-recognition domains of the M subunit of putative type I DNA methyltransferase such as M2.CinURNWORF2828P and M.Mae7806ORF3969P.

Type I restriction-modification system specificity (S) subunit Target Recognition Domain-ConseRved domain (TRD-CR), similar to Lactobacillus delbrueckii subsp. bulgaricus S subunit (S2.LdeBORF1052P) TRD2-CR2; The recognition sequence of Lactobacillus delbrueckii subsp. bulgaricus S subunit (S2.LdeBORF1052P) is undetermined. The restriction-modification (RM) system S subunit consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs. The TRDs each bind to different specific sequences in the DNA. RM systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host genome is protected from cleavage by methylation of specific nucleotides in the target sites. In type I systems, both restriction and modification activities are present in one heteromeric enzyme complex composed of one DNA specificity (S) subunit (this family), two modification (M) subunits and two restriction (R) subunits. This model contains both TRD1-CR1 and TRD2-CR2. It may also include TRD-CR-like sequence-recognition domains of various type II restriction enzymes and methyltransferases and type I DNA methyltransferases.

Type I restriction-modification system specificity (S) subunit TRD-CR, similar to Lactococcus lactis subsp. lactis Dephy 1 S subunit (S.Lla161ORF747P) TRD1-CR1, and Lactococcus lactis IO-1 S subunit (S2.LlaIO1ORF1141P) TRD2-CR2; The recognition sequences of Lactococcus lactis subsp. lactis Dephy 1 S subunit (S.Lla161ORF747P) and Lactococcus lactis IO-1 S subunit (S2.LlaIO1ORF1141P) are undetermined. The restriction-modification (RM) system S subunit consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs. The TRDs each bind to different specific sequences in the DNA. RM systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host genome is protected from cleavage by methylation of specific nucleotides in the target sites. In type I systems, both restriction and modification activities are present in one heteromeric enzyme complex composed of one DNA specificity (S) subunit (this family), two modification (M) subunits and two restriction (R) subunits. This model contains both TRD1-CR1 and TRD2-CR2. It may also include TRD-CR-like sequence-recognition domains of various type II restriction enzymes and methyltransferases and type I DNA methyltransferases.

Type I restriction-modification system specificity (S) subunit Target Recognition Domain-ConseRved domain (TRD-CR), similar to S.EcoJA65PI TRD1-CR1, S.Fco49512ORF2615P TRD1-CR1, and S.SonIV TRD2-CR2; Escherichia coli UCD_JA65_pb S subunit (S.EcoJA65PI) recognizes 5'... AGCANNNNNNTGA ... 3' while Shewanella oneidensis MR-1 S subunit (S.SonIV) recognizes 5'... TACNNNNNNGTNGT ... 3'. The recognition sequence of Flavobacterium columnare S subunit (S.Fco49512ORF2615P) is undetermined. The restriction-modification (RM) system S subunit consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs. The TRDs each bind to different specific sequences in the DNA. For example, S.EcoJA65PI TRD1 recognizes AGCA/TGCT and S.EcoJA65PI TRD2 recognizes TCA/TGA; S.SonIV TRD1 recognizes TAC/GTA and S.SonIV TRD2 recognizes ACNAC/GTNGT. RM systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host genome is protected from cleavage by methylation of specific nucleotides in the target sites. In type I systems, both restriction and modification activities are present in one enzyme complex composed of one DNA specificity (S) subunit (this family), two modification (M) subunits and two restriction (R) subunits. This model contains both TRD1-CR1 and TRD2-CR2. It may also include TRD-CR-like sequence-recognition domains of various type II restriction enzymes and methyltransferases and type I DNA methyltransferases.

Type I restriction-modification system specificity (S) subunit Target Recognition Domain-ConseRved domain (TRD-CR), similar to Escherichia coli G4/9 S subunit (S.Eco16444ORF1681P) TRD1-CR1 and Zobellia galactanivorans DsiJT S subunit (S.ZgaJTORF2697P)TRD2; The recognition sequences of Escherichia coli G4/9 S subunit (S.Eco16444ORF1681P) and Zobellia galactanivorans DsiJT S subunit (S.ZgaJTORF2697P) are undetermined. The restriction-modification (RM) system S subunit consists of two variable target recognition domains (TRD1 and 2) and two conserved regions (CR1 and CR2) which separate the TRDs.

RM systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host genome is protected from cleavage by methylation of specific nucleotides in the target sites. In type I systems, both restriction and modification activities are present in one heteromeric enzyme complex composed of one DNA specificity (S) subunit (this family), two modification (M) subunits and two restriction (R) subunits. This model contains both TRD1-CR1 and TRD2-CR2. It also includes TRD-CR-like sequence-recognition domains of various putative type II restriction enzymes and methyltransferases and may also include type I DNA methyltransferases.
