Rv2667, (MTCY441.36), len: 252 aa. Possible clpC2,ATP-dependent protease atp-binding subunit, highly similar to Q9X8L2|SCE9.40 hypothetical 27.3 KDA protein from Streptomyces coelicolor (258 aa), FASTA scores: opt: 877,E(): 2.2e-46, (57.25% identity in 255 aa overlap). The second half of the protein is highly similar to N-terminal of several CLP-family proteins e.g. P24428|CLPC_MYCLE|ML0235 probable ATP-dependent CLP protease ATP-binding subunit from Mycobacterium leprae (848 aa), FASTA scores: opt: 307, E(): 3.2e-11, (38.6% identity in 158 aa overlap); O06286|CLPC_MYCTU|Rv3596c|MT3703 [...]

GCN5-related N-acetyltransferase; Rv3027c, (MTV012.42c), len: 281 aa. Probable acetyltransferase. Contains GNAT (Gcn5-related N-acetyltransferase) domain in N-terminal part. See Vetting et al. 2005. Similar, to others e.g. Q9RCY9|SCM10.09c from Streptomyces coelicolor (256 aa), FASTA scores: opt: 498,E(): 7.8e-24, (47.7% identity in 237 aa overlap); BAB50158|MLR3216 from Rhizobium loti (291 aa), FASTA scores: opt: 359, E(): 3.7e-15, (33.35% identity in 246 aa overlap); etc. Start changed since first submission,extended by 25 aa.

Arylamine N-acetyltransferase Nat (arylamine acetylase); Catalyzes the transfer of the acetyl group from acetyl coenzyme A to the free amino group of arylamines and hydrazines. Is able to utilize not only acetyl-CoA, but also n- propionyl-CoA and acetoacetyl-CoA as acyl donors, although at a lower rate. As acetyl-CoA and propionyl-CoA are products of cholesterol catabolism and the nat gene is likely present in the same operon than genes involved in cholesterol degradation, this enzyme could have a role in the utilization and regulation of these CoA species.

Rv1135A, len: 80 aa. Possible acetyl-CoA acetyltransferase (possible gene fragment), highly similar to other acetyl-CoA acetyltransferases e.g. C-terminal part of Rv3556c|Z92774|MTCY6G11_2|MTCY06G11.03|fadA6 acetyl-CoA acetyltransferase from Mycobacterium tuberculosis (386 aa),FASTA scores: opt: 219, E(): 5.7e-09, (63.6% identity in 55 aa overlap).

Rv1074c, (MTV017.27c), len: 405 aa. Probable fadA3,beta-ketoacyl CoA thiolase, highly similar to many involved in beta-oxidation e.g. CAB89028.1|AL353870 beta-ketoadipyl-CoA thiolase from Streptomyces coelicolor (395 aa); P77525|PAAJ_ECOLI probable beta-ketoadipyl CoA thiolase from Escherichia coli (401 aa), FASTA scores: opt: 1034, E(): 5.4e-56, (43.5% identity in 416 aa overlap) and X97452 acetyl-CoA acetyltransferase (thiolase) from Escherichia coli (401 aa), FASTA scores: opt: 1043, E(): 0,(43.4% identity in 415 aa overlap); Q43935|CATF_ACICA beta-ketoadipyl CoA thiolase from Acine [...]

Conserved protein; Rv1867, (MTCY359.06c), len: 494 aa. Conserved protein, some similarity to acetyl CoA synthase and to lipid carriers. FASTA best: E155295 acetyl CoA synthase (388 aa), opt: 213, E(): 4.5e-07, (23.2% identity in 423 aa overlap).

GCN5-related N-acetyltransferase, phosphorylase; Rv3225c, (MTCY07D11.01), len: 474 aa. Conserved hypothetical protein has GNAT (Gcn5-related N-acetyltransferase) domain in N-terminal part (see Vetting et al. 2005) and phosphotransferase domain in C-terminal part. C-terminal part shows similarity to various bacterial phosphotransferases e.g. BAB49093|MLL1809 hypothetical protein from Rhizobium loti (Mesorhizobium loti) (298 aa),FASTA scores: opt: 557, E(): 2.8e-26, (34.55% identity in 295 aa overlap); P14509|KKA8_ECOLI|APHA aminoglycoside 3'-phosphotransferase from Escherichia coli (271 [...]

8-amino-7-oxononanoate synthase 1; Catalyzes the decarboxylative condensation of pimeloyl-[acyl- carrier protein] and L-alanine to produce 8-amino-7-oxononanoate (AON), [acyl-carrier protein], and carbon dioxide (By similarity). Can also use pimeloyl-CoA instead of pimeloyl-ACP as substrate. To a lesser extent, can also utilize D-alanine instead of L-alanine as substrate. Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. BioF subfamily.
