l-methionine sulfoxide

L-Methionine sulfoxide (H-Met(O)-OH) is a metabolite of Methionine that modulates oxidative stress and purinergic signaling parameters, while inducing M1/classical macrophage polarization.

S-Methyl-L-cysteine (S-Methylcysteine) is a natural product serving as a substrate in the methionine sulfoxide reductase A (MSRA) catalyzed antioxidant system, exhibiting neuroprotective, antioxidative, and anti-obesity properties.

SAHO is a sulfoxide form of the methyl donor S-(5'-adenosyl)-L-methionine chloride and a substrate for radical SAM enzymes.1It is reductively cleaved to S-adenosylhomocysteine , 5'-deoxyadenosine , and 5'-thioadenosine sulfenic acid by the radical SAM enzymes NosL or NosN. 1.Mandalapu, D., Ji, X., and Zhang, Q.Reductive cleavage of sulfoxide and sulfone by two radical S-adenosyl-L-methionine enzymesBiochemistry58(1)36-39(2019)

SAHO2is a sulfone form of the methyl donor S-(5'-adenosyl)-L-methionine chloride and is a substrate for radical SAM enzymes.1It is reductively cleaved to 5'-deoxyadenosine and 5'-thioadenosine sulfinic acid by the radical SAM enzymes NosL or NosN. 1.Mandalapu, D., Ji, X., and Zhang, Q.Reductive cleavage of sulfoxide and sulfone by two radical S-adenosyl-L-methionine enzymesBiochemistry58(1)36-39(2019)
