| + | Isovaleryl coenzyme A (IV-CoA) performs a crucial role during development and fruiting-body formation in myxobacteria, which is reflected in the existence of a de novo biosynthetic pathway that is highly upregulated when leucine, the common precursor of IV-CoA, is limited. The final step in de novo IV-CoA biosynthesis is catalyzed by AibC, a medium-chain dehydrogenase/reductase. Here, the crystal structure of AibC from Myxococcus xanthus refined to 2.55 A resolution is presented. The protein adopts two different conformations in the crystal lattice, which is a consequence of partial interaction with the purification tag. Based on this structure, it is suggested that AibC most probably uses a Zn(2+)-supported catalytic mechanism in which NADPH is preferred over NADH. Taken together, this study reveals structural details of the alternative IV-CoA-producing pathway in myxobacteria, which may serve as a base for further biotechnological research and biofuel production. | ||
