Reaction: acetyl-CoA + an N-terminal L-alanyl-[bS18 protein of 30S ribosome] = CoA + an N-terminal N-acetyl-L-alanyl-[bS18 protein of 30S ribosome]
Other name(s): rimI (gene name)
Systematic name: acetyl-CoA:N-terminal L-alanyl-[bS18 protein of 30S ribosome] N-acetyltransferase
Comments: The enzyme, characterized from bacteria, is specific for protein bS18, a component of the 30S ribosomal subunit. cf. EC 2.3.1.267, [ribosomal protein uS5]-alanine N-acetyltransferase.
