Probable bacterioferritin BfrA; Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex.

Probable cytochrome C oxidase assembly factor CtaB; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group.

Rv0958, (MTCY10D7.16c), len: 459 aa. Possible magnesium chelatase, similar to others (especially in N-terminal parts) e.g. NP_296313.1|NC_001263|AE002088_10 putative magnesium protoporphyrin chelatase from Deinococcus radiodurans (487 aa), FASTA scores: opt: 1148,E(): 0, (42.4% identity in 450 aa overlap); Q44498|CHLI_ANAVA magnesium-chelatase subunit CHLI from Anabaena variabilis (338 aa); T31460 probable magnesium chelatase chain I bchI from Heliobacillus mobilis (363 aa); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop).

Probable oxidase; Required for copper resistance. In vitro, oxidizes organic substrates and Fe(2+). May act in vivo by oxidation of toxic periplasmic Cu(+); Belongs to the multicopper oxidase family.

Bacterioferritin BfrB; Iron-storage protein that displays ferroxidase activity, catalyzing the oxidation of Fe(2+) ions into Fe(3+) ions, that can then be deposited as a ferric-oxide mineral core within the central cavity of the protein complex; Belongs to the ferritin family. Prokaryotic subfamily.

NADH-dependent enoyl-[acyl-carrier-protein] reductase InhA (NADH-dependent enoyl-ACP reductase); Enoyl-ACP reductase of the type II fatty acid syntase (FAS- II) system, which is involved in the biosynthesis of mycolic acids, a major component of mycobacterial cell walls. Catalyzes the NADH-dependent reduction of the double bond of 2-trans- enoyl-[acyl-carrier protein], an essential step in the fatty acid elongation cycle of the FAS-II pathway. Shows preference for long-chain fatty acyl thioester substrates (>C16), and can also use 2-trans-enoyl-CoAs as alternative substrates. The mycob [...]
