Enzyme Research
Reports outline enzyme research study results from M. Kirsch et al
July 2nd, 2008
According to recent research published in the Journal of Pineal Research, "Low-molecular-weight S-nitrosothiols (RSNOs) are well known for their capability to transnitrosate cysteine residues of enzymes thereby altering their catalytic activity. It is unknown, however, whether N-nitrosomelatonin (NOMela) which is highly effective in trans nitrosating low-molecular-weight thiols (RSHs) can also alter protein function." "In the present study, we report on such a capability with glyceraldehyde 3-phosphate dehydrogenase (GAPDH) as a target enzyme. Reaction of NOMela with GAPDH resulted in an increase of RSNOs at the expense of RSHs. Somewhat surprisingly, NOMela was...
