Butanoic acid, 2-hydroxy-4-(methylthio)-: ACTIVE
CHICK LIVER HOMOGENATES CATALYZED THE OXIDATION OF 2-HYDROXY-4-(METHYLTHIO)BUTANOIC ACID TO KETOMETHIONINE & BOTH CHICK LIVER SUPERNATANTS & RAT LIVER SUPERNATANTS CONVERTED KETOMETHIONINE TO THE HYDROXY DERIVATIVE OR TO METHIONINE.
IN RAT TISSUE, BOTH FLAVINE COENZYME & GLUTAMINE ARE REQUIRED FOR THE CONVERSION OF 2-HYDROXY-4-METHYLTHIOBUTYRIC ACID INTO METHIONINE. PER GRAM OF TISSUE, THE KIDNEY POSSESSES GREATER CONVERSION ACTIVITY THAN THE LIVER, BRAIN, SMALL INTESTINE, & MUSCLE, ALTHOUGH ON A TOTAL ORGAN BASIS THE LIVER IS THE MOST IMPORTANT. MOST OF THE CONVERSION ACTIVITY IS LOCATED IN THE SUPERNATANT FRACTION OF THE LIVER.
