CommentThis enzyme, FabZ, shows overlapping substrate specificity with FabA with regard to chain length in fatty acid biosynthesis. FabZ works preferentially on shorter chains and is often designated (3R)-hydroxymyristoyl-[acyl carrier protein] dehydratase, although its actual specificity is broader. Unlike FabA, FabZ does not function as an isomerase and cannot initiate unsaturated fatty acid biosynthesis. However, only FabZ can act during the elongation of unsaturated fatty acid chains.
