[S-methylmethioninesulfonium hydrolase activity in plant and animal tissues]. / Izuchenie aktivnosti S-metilmetioninsul'fonii-gidrolazy v rastitel'nykh i zhivotnykh tkaniakh.

ABSTRACT

A gas-chromatographic technique is proposed for determining the activity of S-methylmethionine-sulphonium-salt hydrolase in homogenates of plant and animal tissues. The enzyme was found in flowers, leaves and fruits of different plants. The enzymatic hydrolysis of S-methylmethionine was found for the first time in different organs of animals, liver and kidneys possessing the highest enzyme activity.
