Rv2552c, (MTCY159.04), len: 269 aa. Probable aroE,shikimate 5-dehydrogenase, equivalent to Q9CCS7|AROE|ML0515 putative shikimate 5-dehydrogenase from Mycobacterium leprae (278 aa), FASTA scores: opt: 1452, E(): 1.8e-77,(81.5% identity in 270 aa overlap). Also highly similar,but longer 101 aa, to Q9KH59|AROE putative shikimate dehydrogenase (fragment) from Mycobacterium marinum (148 aa), FASTA scores: opt: 729, E(): 1.3e-35, (76.35% identity in 148 overlap); Q9F7W3|AROE from Mycobacterium ulcerans (148 aa), FASTA scores: opt: 718, E(): 5.9e-35, (75.7% identity in 148 aa overlap). And al [...]

Shikimate kinase AroK (SK); Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate. Belongs to the shikimate kinase family.

Probable chorismate synthase AroF (5-enolpyruvylshikimate-3-phosphate phospholyase); Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

30S ribosomal protein S15 RpsO; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA.

Chorismate mutase; Catalyzes the Claisen rearrangement of chorismate to prephenate. May play some role in the pathogenicity.

Probable isochorismate synthase EntC (isochorismate hydroxymutase) (enterochelin biosynthesis); Catalyzes the conversion of chorismate to isochorismate.

Isochorismate synthase MbtI; Involved in the incorporation of salicylate into the virulence-conferring salicylate-based siderophore mycobactin. Catalyzes the initial conversion of chorismate to yield the intermediate isochorismate (isochorismate synthase activity), and the subsequent elimination of the enolpyruvyl side chain to give salicylate (isochorismate pyruvate-lyase activity). In the absence of magnesium, MbtI displays a chorismate mutase activity and converts chorismate to prephenate.

Rv1848, (MTCY359.25c), len: 100 aa. UreA, urease gamma subunit. Similar to URE3_MYCTU|P50043 from Mycobacterium tuberculosis (100 aa), FASTA scores: opt: 630, E(): 1.3e-36, (99.0% identity in 100 aa overlap). Belongs to the urease gamma subunit family.

Rv1973, (MTV051.11), len: 160 aa. Possible conserved Mce-associated membrane protein. Probably part of mce3 operon. Similar to several other proteins from Mycobacterium tuberculosis e.g. Rv1362c|Z75555|MTCY02B10.26C (220 aa), FASTA scores: opt: 378, E(): 2.8e-19, (50.0% identity in 128 aa overlap); Rv1363c; Rv0177 (near Mce operon 1); etc. Contains possible N-terminal signal sequence or membrane anchor. Predicted to be an outer membrane protein (See Song et al., 2008).
