Protein Family Models

This domain is found in a wide range of extracellular proteins. It is found tandemly repeated in up to 8 copies. It is found in the N-terminus of peptidases belonging to the M26 family which cleave human IgA. The domain is also found in proteins involved in metabolism of bacterial cell walls suggesting this domain may have an adhesive function. [1]. 18992255.

This short presumed domain contains three conserved aspartate residues, hence the name 3D. It has been shown to be part of the catalytic double psi beta barrel domain of MltA [1]. [1]. 16139297.

This domain normally occurs as tandem repeats; however it is found as a single copy in the S. cerevisiae DNA-binding nuclear protein YCR593 (Swiss:P25357). This protein is involved in sporulation part of the SET3C complex, which is required to repress early/middle sporulation genes during meiosis ([2]). The bacterial proteins are likely to be involved in a cell wall function as they are found in conjunction with the Pfam:PF07501 domain, which is involved in various cell surface processes. This domain is also present in the resuscitation-promoting factors RpfB from Mycobacterium tuberculosis and Rpf2 from Corynebacterium glutamicum. These are factors that stimulate resuscitation of dormant cells [3]. This domain has a beta grasp fold. Structural description of this domain revealed a structural conservation between these domains and ubiquitin, hence it is termed UBL-G5 [4]. [1]. 12625841.

G5 and 3D (Asp-Asp-Asp) domain-containing protein contains a G5 domain with similarity to resuscitation-promoting factor, a cell-wall glycosidase that cleaves cell-wall peptidoglycan, and a C-terminal 3D domain that contains the critical active site aspartate of MltA-like lytic transglycosylases; also contains DUF348 domains
