General annotation
FunctionAcetylates the N-terminal alanine of ribosomal protein S18 [catalytic activity: acetyl-CoA + ribosomal-protein L-alanine = CoA + ribosomal-protein N-acetyl-L-alanine].
ProductRibosomal-protein-alanine acetyltransferase RimI (acetylating enzyme for N-terminal of ribosomal protein S18)
CommentsRv3420c, (MTCY78.09), len: 158 aa. Probable rimI, ribosomal-protein-alanine acetyltransferase, contains GNAT (Gcn5-related N-acetyltransferase) domain. See Vetting et al. 2005. Equivalent to C-terminal part of Q49857|YY21_MYCLE|ML0378|B229_C1_170 hypothetical 38.0 KDA protein from Mycobacterium leprae (359 aa), FASTA scores: opt: 772, E(): 2.7e-44, (72.1% identity in 154 aa overlap). Similar notably to ribosomal-protein-alanine acetyltransferases e.g. Q9AC11|CC0058 from Caulobacter crescentus (150 aa), FASTA scores: opt: 223, E(): 4.9e-08, (37.5% identity in 136 aa overlap); Q9KFD4|BH0547 from Bacillus halodurans (151 aa), FASTA scores: opt: 222, E(): 5.8e-08, (35.2% identity in 142 aa overlap); Q9PG61|XF0441 from Xylella fastidiosa (156 aa), FASTA scores: opt: 207, E(): 5.9e-07, (32.2% identity in 149 aa overlap); Q9HVB7|RIMI|PA4678 from Pseudomonas aeruginosa (150 aa), FASTA scores: opt: 203, E(): 1.1e-06, (32.45% identity in 151 aa overlap); P09453|RIMI_ECOLI|B4373 from Escherichia coli strain K12 (148 aa), FASTA scores: opt: 196, E(): 3.1e-06, (33.55% identity in 149 aa overlap); etc. Belongs to the acetyltransferase family, RIMI subfamily.
