Enzymic Introduction of the Methyl Ester Groups of Pectin*

A particulate preparation obtained from Phoseolus aweus shoots contains an enzyme capable of transferring the 14Clabeled methyl groups from S-adenosyl-L-methionine to the carbozyl groups of polygalacturonic acid, which seems to be present in the same particulate material. The introduction of the methyl ester groups is optimal at pH 6.8 and does not require divalent ions. S-IV-Methyltetrahydrofo...

The pH-dependence of enzymic ester hydrolysis.

The esterases of animal tissues have generally been characterized by their substrate specificity and by their behaviour towards various inhibitors. The irreversible inhibition by organic phosphates, which is due to phosphorylation of the active group (Burgen, 1949; Wilson & Bergmann, 1950a; Aldridge, 1953d), is a common property of most esterases, an interesting exception being the Aesterase of...
