This family of proteins is structurally similar to proteins with the Bacillus chorismate mutase-like (BCM-like) fold. This structure, combined with its genomic context, suggest that it has a role in amino acid synthesis [1].

1: Structures of the first representatives of Pfam family PF06684 (DUF1185) reveal a novel variant of the Bacillus chorismate mutase fold and suggest a role in amino-acid metabolism.
