Thus, successively transfers approximately 28 galactofuranosyl (Galf) residues from UDP-galactofuranose (UDP-Galf) onto the galactofuranosyl- galactofuranosyl-rhamnosyl-GlcNAc-diphospho-decaprenol (Galf-Galf-Rha- GlcNAc-PP-C50) acceptor produced by GlfT1, with alternating 1->5 and 1->6 links, forming a galactan domain with approximately 30 galactof [...] (637 aa) |
| | glf | UDP-galactopyranose mutase; Catalyzes the interconversion through a 2-keto intermediate of uridine diphosphogalactopyranose (UDP-GalP) into uridine diphosphogalactofuranose (UDP-GalF) which is a key building block for cell wall construction in Mycobacterium tuberculosis. (399 aa) |
| | papA2 | Possible conserved polyketide synthase associated protein PapA2; Catalyzes the acylation of trehalose-2-sulfate by adding the palmitoyl group at the 2'-position to yield the intermediate trehalose- 2-sulfate-2'-palmitate (SL659) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family. (468 aa) |
| | sap | Probable conserved integral membrane protein; Required for the transport across the inner membrane of sulfolipid-1 (SL-1), which is a major cell wall lipid of pathogenic mycobacteria. Could also transport SL1278 (2-palmitoyl-3-(C43)- phthioceranyl-alpha, alpha'-D-trehalose-2'-sulfate), which is the precursor of SL-1. May potentiate SL-1 levels and confer specificity for sulfolipids over structurally similar glycolipids. (237 aa) |
| | mmpL8 | Conserved integral membrane transport protein MmpL8; Required for the biosynthesis and the transport across the inner membrane of sulfolipid-1 (SL-1), which is a major cell wall lipid of pathogenic mycobacteria. Could also transport SL1278 (2-palmitoyl-3- (C43)-phthioceranyl-alpha, alpha'-D-trehalose-2'-sulfate), which is the precursor of SL-1. Required for virulence. (1089 aa) |
| | papA1 | Conserved polyketide synthase associated protein PapA1; Catalyzes the acylation of trehalose-2-sulfate-2'-palmitate (SL659) by adding the (hydroxy)phthioceranoyl group at the 3'-position to yield the diacylated intermediate 2-palmitoyl-3-(C43)-phthioceranyl- alpha, alpha'-D-trehalose-2'-sulfate (SL1278) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family. (511 aa) |
| | pks2 | Polyketide synthase Pks2; Catalyzes the synthesis of the hepta- and octamethyl phthioceranic acids and/or hydroxyphthioceranic acids that are the major acyl constituents of sulfolipids. (2126 aa) |
| | mviN | Probable conserved transmembrane protein; Essential for cell growth and peptidoglycan synthesis. In the N-terminal section; belongs to the MurJ/MviN family. (1184 aa) |
| | cwlM | Probable peptidoglycan hydrolase; Cell-wall hydrolase that hydrolyzes the amide bond between N- acetylmuramic acid and L-alanine in cell-wall glycopeptides. Is able to lyse whole mycobacteria, release peptidoglycan from the cell wall of M.luteus and M.smegmatis, and cleave N-acetylmuramoyl-L-alanyl-D- isoglutamine, releasing free N-acetylmuramic acid and dipeptide. (406 aa) |
| | Rv3920c | Rv3920c, (MTV028.11c), len: 187 aa. Conserved protein, similar to jag protein, equivalent to Q9L7M2 hypothetical 20.1 KDA protein from Mycobacterium paratuberculosis (183 aa), FASTA scores: opt: 1004, E(): 7.3e-52, (85.05% identity in 187 aa overlap); and Q50204|ML2709 hypothetical protein similar to jag protein SPOIIIJ associated protein in bacillus subtilis from Mycobacterium leprae (193 aa), FASTA scores: opt: 871, E(): 4.4e-44, (73.05% identity in 193 aa overlap). Also similar to other bacterial proteins e.g. O54595|STH24.06|jag jag-like protein from Streptomyces coelicolor (170 aa [...] (187 aa) |
| | yidC | Probable conserved transmembrane protein; Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins. Aids folding of multispanning membrane proteins (By similarity). (366 aa) |
