Chain A (O81226_CARPA | O81226)


GO:0016603	glutaminyl-peptide cyclotransferase activity	Catalysis of the reaction: L-glutaminyl-peptide = 5-oxoprolyl-peptide + NH3.
GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
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).
