EC 2.3.1.266

Accepted name: [ribosomal protein S18]-alanine N-acetyltransferase

Reaction: acetyl-CoA + an N-terminal L-alanyl-[S18 protein of 30S ribosome] = CoA + an N-terminal N-acetyl-L-alanyl-[S18 protein of 30S ribosome]

Other name(s): rimI (gene name)

Systematic name: acetyl-CoA:[S18 protein of 30S ribosome]-L-alanine N-acetyltransferase

Comments: The enzyme, characterized from the bacterium Escherichia coli, is specific for protein S18, a component of the 30S ribosomal subunit. cf. EC 2.3.1.267, [ribosomal protein S5]-alanine N-acetyltransferase.
