Liver Betaine-Homocysteine S-Methyltransferase Activity Undergoes a Redox Switch at the Active Site Zinc
Using a redox-inert methyl acceptor, we show that betaine-homocysteine S-methyltransferase (BHMT) requires a thiol reducing agent for activity. Short-term exposure of BHMT to reducing agent-free buffer inactivates the enzyme without causing any loss of its catalytic zinc. Activity can be completely...
