Substrates: poor substrate. S-HPCDH3 cannot bind hydroxypropyl-CoM with CoM oriented properly in the sulfonate-binding pocket that consists of residues R211 and K214. R-hydroxypropyl-CoM binds to S-HPCDH3 with a 290-fold lower affinity but in an orientation where the hydroxyl and hydrogen on C2 can be more properly aligned with tyrosine 156 and NAD+, such that kcat decreases by 4.5-fold relative to the natural substrate S-hydroxypropyl-CoM
