Proteasome alpha subunit PrcA; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.tuberculosis proteasome is able to cleave oligopeptides not only after hydrophobic but also after basic, acidic and small neutral residues. In complex with the ATPase Mpa, degrades protein targets conjugated to a prokaryotic ubiquitin-like protein (Pup). Among the identified substrates of the M.tuberculosis proteasome are the pupylated FabD, PanB and Mpa proteins. One function of the proteasome is to contribute to M.tuberculosis ability [...]

Conserved protein; Rv1100, (MTV017.53), len: 233 aa. Conserved protein,slightly similar to Rv1906c|MTCY180.12 hypothetical protein from Mycobacterium tuberculosis (156 aa), FASTA scores: opt: 122, E(): 6.9, (27.4% identity in 135 aa overlap). Equivalent to AL049491|MLCB1222_9 Mycobacterium leprae (257 aa) (63.8% identity in 257 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Conserved hypothetical protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation. Belongs to the Iojap/RsfS family.

Rv2908c, (MTCY274.40c), len: 80 aa. Conserved hypothetical protein, equivalent to O33015|YT08_MYCLE from Mycobacterium leprae (80 aa), FASTA scores: opt: 492, E(): 3.1e-29, (93.75% identity in 80 aa overlap). Also highly similar to others e.g. O69880|YE09_STRCO from Streptomyces coelicolor (79 aa), FASTA scores: opt: 356, E(): 3e-19,(71.6% identity in 74 aa overlap); Q9KA12|BH2482 protein from Bacillus halodurans (76 aa), FASTA scores: opt: 220,E(): 2.9e-09, (48.6% identity in 72 aa overlap); O31738|YLQC_BACSU hypothetical 9.1 KDA protein from Bacillus subtilis (81 aa), FASTA scores: o [...]

Conserved protein; Interacts with the core proteasome alpha-subunit (PrcA) through its C-terminal hydrophobic-tyrosine-X motif (HbYX motif). Interaction of Bpa with the proteasome stimulates proteosomal peptidase and casein degradation activity, which suggests Bpa could play a role in the removal of non-native or damaged proteins by influencing the conformation of the proteasome complex upon interaction. Can inhibit degradation of Pup-tagged substrates in vitro by competing with Mpa for association with the proteasome; Belongs to the Bpa family.

Conserved protein; Rv3773c, (MTCY13D12.07c), len: 194 aa. Conserved protein, highly similar to C-terminal end of O53773|Rv0576|MTV039.14 possible transcriptional regulator from Mycobacterium tuberculosis (434 aa), FASTA scores: opt: 575, E(): 8.3e-30, (47.4% identity in 192 aa overlap); and some similarity with other proteins from Mycobacterium tuberculosis e.g. P71985|Rv1727|MTCY04C12.12 (189 aa) FASTA scores: opt: 176, E(): 0.00022, (31.1% identity in 180 aa overlap).

Possible succinyltransferase in the GCN5-related N-acetyltransferase family; May function as a succinyl-CoA transferase.

Glutamate synthase [NADPH] large chain; Rv3859c, (MTCY01A6.09), len: 1527 aa.
