THERMUS MALTOGENIC AMYLASE IN COMPLEX WITH BETA-CD

Overview

Over 20 enzymes denoted as cyclomaltodextrinase, maltogenic amylase, or, neopullulanase that share 40-86% sequence identity with each other are, found in public data bases. These enzymes are distinguished from typical, alpha-amylases by containing a novel N-terminal domain and exhibiting, preferential substrate specificities for cyclomaltodextrins (CDs) over, starch. In this research field, a great deal of confusion exists regarding, the features distinguishing the three groups of enzymes from one another., Although a different enzyme code has been assigned to each of the three, different enzyme names, even a single differentiating enzymatic property, has not been documented in the literature. On the other hand, an, outstanding question related to this issue concerns the structural basis, ... [(full description)]
