The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout

After the MOCS2A dimer is loaded with two sulfur atoms, their sequential deposition on the precursor Z molecule, with ring cleavage, is catalyzed by the MOCS2B half of the MOCS2 tetramer (Leimkuhler et al, 2003; Wuebbens & Rajagopalan, 2002).
