Molybdenum ion transfer onto molybdopterin Authored: Stephan, R, 2010-09-05 EC Number: 2 Edited: Jassal, B, 2010-09-08 Gephyrin, which stabilizes receptors on neuronal membranes, also catalyzes the transfer of a molybdenum ion onto the cofactor. The mechanism was elucidated in plants but, as the pathway is highly conserved, human gephyrin can complement missing plant proteins. Doubts remain about the actual molybdenum donor, probably molybdate, and whether a copper ion is possibly bound and removed (Stallmeyer et al, 1999).
