Isolated nucleic acid (I) that encodes any of 50 amino acid sequences (II) that have, at specific positions, an amino acid (aa) alteration. The specification includes (i) a table identifying the function of (II) and the nature/position of the amino acid exchange and (ii) sequences for (I) and (II). Independent claims are also included for the following: (1) vector that contains at least one (I); (2) host cell transfected with at least one vector of component (1); and (3) preparing fine chemicals by culturing cells of component (2). |
