Product stereochemistry and some inhibitors of the α-arabinofuranosidases of Monilinia fructigena

Abstract

That the initial product of the title enzymes is α-L-arabinofuranose is shown by the detection of methyl α-L-arabinofuranoside when the hydrolysis of p-nitrophenyl α-L-arabinofuranoside is carried out at a concentration of 0.5–1.5M in methanol. A study of competitive inhibitors indicates that L-arabinono-1,4-lactone is unusually tightly bound.
