HIBCH Hydrolyzes 3-hydroxyisobutyryl-CoA (HIBYL-CoA), a saline catabolite. Has high activity toward isobutyryl-CoA. Could be an isobutyryl-CoA dehydrogenase that functions in valine catabolism. Also hydrolyzes 3-hydroxypropanoyl-CoA. Belongs to the enoyl-CoA hydratase/isomerase family. Highly expressed in liver and kidney, also detected in heart, muscle and brain (at protein level). Not detected in lung. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
