Research Abstract |
I discovered an unique glycoside hydrolases family which contains inverting- and retaining-catalytic enzymes. This divergence was due to the simple difference of the position of catalytic residues. We attempted to convert the catalytic mechanism of these enzyme each other. However, the attempt was failed. These results indicated that two similar enzymes diverged from a common ancestor in early stage of evolution and each enzyme evolved in different ways.
