In Vitro and in Vivo Effects of Alkyl Nitrites on Methionine Synthase from Mouse Kidney and Liver

Pteridines, 1989
The effect of butyl and isoamyl nitrites on methionine synthase from mouse kidney and liver was investigated. A strong specific inhibition of the enzyme (50% at 7.3 x 10 4 M nitrites for kidney methionine synthase) was found.
