ArsR repressor protein; Involved in the regulation of lipid metabolism and hypoxic response. Positively regulates transcription of various genes, such as phoP, groEL2 and dosR. Negatively regulates its own transcription. Acts by binding to a specific palindromic sequence motif in promoter regions.

Conserved hypothetical protein; Rv1775, (MTCY25C11.02), unknown, len: 272 aa. Conserved hypothetical protein, similar to O28806|AF1466 conserved hypothetical protein from Archaeoglobus fulgidus (255 aa), FASTA scores: opt: 364, E(): 1e-17, (29.2% identity in 267 aa overlap).

Rv2033c, (MTV018.20), len: 280 aa. Conserved hypothetical protein, similar to many.

Decaprenylphosphoryl-D-2-keto erythro pentose reductase; Component of the DprE1-DprE2 complex that catalyzes the 2- step epimerization of decaprenyl-phospho-ribose (DPR) to decaprenyl- phospho-arabinose (DPA), a key precursor that serves as the arabinose donor required for the synthesis of cell-wall arabinans. DprE1 catalyzes the first step of epimerization, namely FAD-dependent oxidation of the C2' hydroxyl of DPR to yield the keto intermediate decaprenyl-phospho-2'-keto-D- arabinose (DPX). The intermediate DPX is then transferred to DprE2 subunit of the epimerase complex, most probab [...]

Decaprenylphosphoryl-beta-D-ribose 2'-oxidase; Component of the DprE1-DprE2 complex that catalyzes the 2- step epimerization of decaprenyl-phospho-ribose (DPR) to decaprenyl- phospho-arabinose (DPA), a key precursor that serves as the arabinose donor required for the synthesis of cell-wall arabinans. DprE1 catalyzes the first step of epimerization, namely FAD-dependent oxidation of the C2' hydroxyl of DPR to yield the keto intermediate decaprenyl-phospho-2'-keto-D- arabinose (DPX). The intermediate DPX is then transferred to DprE2 subunit of the epimerase complex, most probably through [...]

Rv2570, (MTCY227.31c), len: 129 aa. Conserved hypothetical protein, similar to Q98GQ7|MLR3218 hypothetical protein from Rhizobium loti (Mesorhizobium loti) (133 aa), FASTA scores: opt: 174, E(): 9.6e-05,(32.25% identity in 124 aa overlap); Q9A390|CC3314 hypothetical protein from Caulobacter crescentus (129 aa),FASTA scores: opt: 155, E(): 0.0017, (33.35% identity in 108 aa overlap); and Q9A2Y0|CC3426 hypothetical protein from Caulobacter crescentus (120 aa), FASTA scores: opt: 144, E(): 0.0083, (32.95% identity in 91 aa overlap).

Rv2622, (MTCY01A10.10c), len: 273 aa.

Arabinofuranosyltransferase AftA; Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall. Catalyzes the addition of the first key arabinofuranosyl (Araf) residue from the sugar donor decaprenyl-phospho-arabinose (DPA) on the C-5 of a 6-linked galactofuranosyl (Galf) of the galactan domain, thus 'priming' the galactan for further elaboration by other arabinofuranosyltransferases. It is not able to add an Araf residue to a terminal Galf. Belongs to the glycosyltransf [...]

Rv3192, (MTV014.36), len: 153 aa. Conserved hypothetical ala- and pro-rich protein, with weak similarity to N-terminal half of several proteins e.g. Q11030|YD60_MYCTU|Rv1360|MT1405|MTCY02B10.24 hypothetical 37.3 KDA protein from Mycobacterium tuberculosis (340 aa),FASTA scores: opt: 245, E(): 3.7e-08, (33.1% identity in 157 aa overlap); O30260|AF2411 conserved hypothetical protein from Archaeoglobus fulgidus (363 aa), FASTA scores: opt: 144, E(): 0.072, (32.6% identity in 92 aa overlap); Q9ZA30|GRA-ORF29 putative FMN-dependent monooxygenase from Streptomyces violaceoruber (343 aa), FAS [...]
