When polymorphic amino acid sequences are present in the enzymes, the enzymes are inadequate for transfer of the biochemical unit to a product. In essence, the enzyme is disabled and therefore cannot facilitate product produ ...

To avoid degradation of the PR–RT by autocatalytic activity of the PR, a mutant enzyme was constructed harboring an active site mutation in the PR region (D24A), which leads to an inactive PR. Thus the AZT-resistant mutants also contain the D24A mutation in the PR. The AZT-resistance mut ...

In this reaction, the near-UV/blue light photon is used to excite FADI-I- and flavin in the excited state then donates an electron to the CPD and thus FAD is essential for the reaction. The CPD photolyase gene has been isolated from 13 organisms and, on the basis ...
