NAD(P)+ transhydrogenase (Re/Si-specific)  M-CSA #496

NAD(P) transhydrogenase, a tetramer composed of 2 alpha and 2 beta subunits, is an integral membrane protein that couples the proton transport across the membrane to the reversible transfer of hydride ion equivalents between NAD and NADP. The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane. May play a role in reactive oxygen species (ROS) detoxification in the adrenal gland.
