Abstract excerpt

The mutant strain PN-120 of Cellulomonas flavigena produces a ss-glucosidase that is 10-fold more active than the corresponding enzyme isolated from the parental strain. These enzymes were partially purified through Q Sepharose and Bio-Gel filtration. A single protein band was detected on polyacrylamide-gel electrophoresis/zymogram using 4-methylumbelliferyl-beta-D-glucoside. On sodium dodecyl sulfate-PAGE, the...
