Conserved hypothetical protein; Protein yhhW. SPROT:P46852: 51% identity, 69% similarity entry represents N-terminal domain of Pirin proteins from both eukaryotes and prokaryotes. The function of Pirin is unknown but the gene coding for this protein is known to be expressed in all tissues in the human body InterPro; IPR007113; Cupin_sup. InterPro; IPR003829; Pirin_N. Pfam; PF02678; Pirin; TIGR00292: thiazole biosynthesis enzyme Absence of transmembrane helices (TMHMM predicted); Function unclear.

Conserved hypothetical membrane protein. Homology to PA2403 of Pseudomonas aeruginosa of 38% (trembl|Q8G8F6). Has 3 copies of PF03929, PepSY-associated TM helix;IPR005625 pEPsy_tm; This domain represents a conserved TM helix found in bacterial proteins. Has PF03413, Peptidase propeptide and YPEB domain; IPR005075,Propep_PepSY:This region is likely to have an protease inhibitory function (personal obs:C Yeats). This region is likely to have an protease inhibitory function (personal obs:C Yeats). This model is likely to miss some members of this family as the separation from signal to no [...]

Conserved hypothetical membrane protein. Homology to NE0537 of Nitrosomonas europaea of 40% (trembl|Q82WX0(SRS)). no domains predicted. signal peptide. 3 TMHs; Conserved hypothetical protein.

Conserved hypothetical protein; Part of the MsrPQ system that repairs oxidized periplasmic proteins containing methionine sulfoxide residues (Met-O), using respiratory chain electrons. Thus protects these proteins from oxidative-stress damage caused by reactive species of oxygen and chlorine generated by the host defense mechanisms. MsrPQ is essential for the maintenance of envelope integrity under bleach stress, rescuing a wide series of structurally unrelated periplasmic proteins from methionine oxidation. The catalytic subunit MsrP is non-stereospecific, being able to reduce both (R [...]

Conserved hypothetical membrane protein. Homology to VPA0043 of Vibrio parahaemolyticus of 64% (trembl|Q87K55). Pfam: TQO small subunit DoxD. DoxD is a subunit of the terminal quinol oxidase present in the plasma membrane of Acidianus ambivalens, with calculated molecular mass of 20.4 kDa. Thiosulphate:quinone oxidoreductase (TQO) is one of the early steps in elemental sulphur oxidation. A novel TQO enzyme was purified from the thermo-acidophilic archaeon Acidianus ambivalens and shown to consist of a large subunit (DoxD) and a smaller subunit (DoxA). The DoxD- and DoxA-like two subuni [...]
