Gene Ontology (5, 5)

Asymmetric/Biological Unit(hide GO term definitions)

Chain A,B (PAIA_THEAC | Q9HL57)

molecular function
	GO:0008080	N-acetyltransferase activity	Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
	GO:0004145	diamine N-acetyltransferase activity	Catalysis of the reaction: acetyl-CoA + an alkane-alpha,omega-diamine = CoA + an N-acetyldiamine.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
	GO:0016746	transferase activity, transferring acyl groups	Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
biological process
	GO:0043939	negative regulation of sporulation	Any process that stops, prevents, or reduces the frequency, rate or extent of sporulation, the process whose specific outcome is the progression of a spore over time, from its initiation to the mature structure.
