This family includes SnoaL [1] a polyketide cyclase involved in nogalamycin biosynthesis. This family was formerly known as DUF1486. The proteins in this family adopt a distorted alpha-beta barrel fold [1]. Structural data together with site-directed mutagenesis experiments have shown that SnoaL has a different mechanism to that of the classical aldolase for catalysing intramolecular aldol condensation [1].
