CIRCULARLY PERMUTED (1-3,1-4)-BETA-D-GLUCAN 4-GLUCANOHYDROLASE CPA16M-84
OverviewOverview
The 1,3-1,4-beta-glucanases from Bacillus macerans and Bacillus, licheniformis, as well as related hybrid enzymes, are stable proteins, comprised of one compact jellyroll domain. Their structures are studied in, an effort to reveal the degree of redundancy to which the, three-dimensional structure of protein domains is encoded by the amino, acid sequence. For the hybrid 1,3-1,4-beta-glucanase H(A16-M), it could be, shown recently that a circular permutation of the sequence giving rise to, the variant cpA16M-59 is compatible with wildtype-like enzymatic activity, and tertiary structure (Hahn et al., Proc. Natl. Acad. Sci. USA, 91:10417-10421, 1994). Since the circular permutation yielding cpA16M-59, mimicks that found in the homologous enzyme from Fibrobacter succinogenes, the question ...
