N-Utilization Substance G (NusG) N terminal (NGN) insert and Lin0431 are part of DUF1312; ...
 36-109 7.18e-19

N-Utilization Substance G (NusG) N terminal (NGN) insert and Lin0431 are part of DUF1312; Domains of Unknown Function 1312 (DUF1312) are represented in at least 71 bacterial species with no functional annotation. Included in this family are N-Utilization Substance G (NusG) N terminal (NGN) insert and Lin0431, having similar structure and surface features that appear to be conserved across these domain families, suggesting similar function. NusG contains NGN at the N-terminus and Kyrpides Ouzounis and Woese (KOW) repeats at the C-terminus in bacteria and archaea, and this insert (often known as Domain II) is found in several bacteria. Lin0431 is similar to NGN-insert but does ot contain the disulphite bridge

NGN-insert domain found between N-terminal domain (D1) and C-terminal KOW domain (DIII) ...
 36-113 7.81e-12

NGN-insert domain found between N-terminal domain (D1) and C-terminal KOW domain (DIII) repeats of some N-Utilization Substance G (NusG) N-terminal (NGN); This family contains a unique insert (domain II, DII) found between the highly conserved N-terminal domain (NGN, domain I, D1) and C-terminal Kyrpides Ouzounis and Woese domain (KOW, domain III, DIII) repeats of some N-Utilization Substance G (NusG) N-terminal (NGN) proteins in bacteria such as Aquifex aeolicus NusG (AaeNusG). NusG was originally discovered as having an N-dependent antitermination enhancing activity in Escherichia coli, and has since been shown to have a variety of functions such as being involved in RNA polymerase elongation and Rho-termination. Orthologs of NusG gene exist in bacteria, but their functions and requirements are diverse. The function of DII is as yet unknown, and belongs to Domains of Unknown Function 1312 (DUF1312).

Listerrria innocua Lin0431 is similar to the N-Utilization Substance G (NusG) N terminal (NGN) ...
 71-109 7.82e-10

Listerrria innocua Lin0431 is similar to the N-Utilization Substance G (NusG) N terminal (NGN) insert (DII); This family contains domains homologous to Listeria innocua Lin0431, a protein that is similar to the N-Utilization Substance G (NusG) N terminal (NGN) insert (domain II, DII). Lin0431 and Aquifex aeolicus NusG DII (AaeNusG DII ) have similar structure and similar basic charged surface distributions that may bind negatively charged nucleic acids and/or another anionic binding partner, suggesting a possible role in transcription/translation regulating functions. Despite these two domains having low sequence similarity, the NusG DII and DUF1312 domain families may have diverged from common evolutionary ancestral proteins, and may have similar biochemical functions.
