Abstract
An Escherichia coli (ATCC 68319) containing a gene encoding a novel maltogenic amylase of Bacillus licheniformis (BLMA), wherein said gene has a length of about 3.5 kb; said gene expresses a gene product capable of hydrolyzing cyclodextrin, pullulan, as well as starch at an optimum temperature of about 50.degree. C. at a pH of about 7; said gene product has sugar transferase activity in the presence of glucose; and said Escherichia coli produces said gene product optimally when grown in Luria broth, for 24 hours, at 37.degree. C.
