Accepted name: 2-hydroxyacyl-CoA lyase
Reaction: (1) a 2-hydroxy-3-methyl-Cn-fatty-acyl-CoA = a 2-methyl-branched Cn-1-fatty aldehyde + formyl-CoA
(2) a (2R)-2-hydroxy-Cn-long-chain fatty acyl-CoA = a Cn-1-long-chain fatty aldehyde + formyl-CoA
Other name(s): HACL1 (gene name); 2-hydroxyphytanoyl-CoA lyase; 2-HPCL
Systematic name: 2-hydroxy-3-methyl fatty-CoA formyl-CoA lyase (2-methyl branched fatty aldehyde-forming)
Comments: Requires Mg2+ and thiamine diphosphate. This peroxisomal enzyme, found in animals, is involved in the α-oxidation of 3-methyl-branched fatty acids like phytanic acid and the shortening of 2-hydroxy long-chain fatty acids.
