[Physiology and biochemistry of streptomycetes. IX. Hydrolysis of cyclohexyl, carbohydrate-and aryl-esters by a carboxyl-esterase from cultures of Streptomyces hygroscopicus JA 6599].

Carboxylesterase in cell-free extracts of Streptomyces hygroscopicus was characterized with cyclohexylacetate and beta-penta-acetyl-D-glucose as as substrates. After concentrating the enzyme, activity with alpha/beta-methyl-4-O-propionyl-L-mycarosid as substrate was also observed. The influence of enzyme effectors was studied. Esterase activity was also found in the culture filtrate of. S. hygroscopicus.
