Sulfur transfer onto MOCS2A is closely preceded by its adenylylation and deadenylylation. After release of MOCS2A-CO-S(1-), two cysteines on MOCS3 form a disulfide bridge. This means that MOCS3 has to be reduced to be able to participate in the next round. The reducing agent is not known (Marelja et al, 2008).
