MODIFIED .ALPHA.-AMYLASES HAVING ALTERED CALCIUM BINDING PROPERTIES |
| 摘要 |
Novel .alpha.-amylase enzymes are disclosed in which a new calcium binding site is modified by chemically or genetically altering residues associated with that calcium binding site. The novel .alpha.-amylases have altered performance characteristics, such as low pH starch hydrolysis performance, stability and activity profiles.
