The cofactor requirements of sarcosine oxidase.
It has been established that the enzyme, sarcosine oxidase, found in the mitochondria of rat liver and elsewhere (I), catalyzes the following over-all reaction (2, 3) : sarcosine + $02 = glycine + serine + HCHO. The cofactor requirements of this reaction have not been established, although Mackenzie (1) has mentioned unpublished results which seemed to indicate that a folic acid deficiency in r...
متن کاملTHE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
متن کاملCrystal Structure of Heterotetrameric Sarcosine Oxidase
Introduction The concentration of serum creatinine is widely used as an indicator of renal function. Sarcosine oxidase (SO) has been used in the enzymatic determination of creatinine in the clinical laboratory. SO has been isolated from various bacterial strains. It was first purified from Corynebacterium sp. U-96 (SO-U96) and shown to be a heterotetrameric enzyme. SO-U96 is a complex, bifuncti...
متن کاملStudies on a Sarcosine Oxidase of Bacterial Origin
A "sarcosine oxidase" was prepared from a creatinine-decomposing strain of Pseudomonas aeruginosa. The enzyme is inactivated by drying, lyophilization, and dialysis against distilled water. No dialyzable cofactor was found. Optimal activity of the enzyme is reached at pH 7.8. Enzyme activity is directly proportional to enzyme concentration and also to substrate concentration up to the point of ...
متن کاملAlteration of L-proline oxidase activity of sarcosine oxidase and a structural interpretation
Sarcosine oxidase (EC 1.5.3.1; sarcosine:oxygen oxidoreductase [demethylating]) is a flavoprotein that catalyses the oxidative demethylation of sarcosine to yield glycine, formaldehydethe, and hydrogen peroxide. This enzyme is involved in the bacterial metabolism of creatinine with the related enzymes, creatininase and creatinase. It is industrially important and is used with creatininase and c...
