Two sets of paralogous genes encode the enzymes involved in the early stages of clavulanic acid and clavam metabolite biosynthesis in Streptomyces clavuligerus.

Transferring alkyl or aryl groups, other than methyl groups (only sub-subclass identified to date)
The enzyme requires thiamine diphosphate and catalyses the first step in the clavulanic-acid-biosynthesis pathway. The 2-hydroxy-3-oxo group transferred from glyceraldehyde 3-phosphate is isomerized during transfer to form the 2-carboxyethyl group.
