mutants overexpressed in Escherichia coli Homo sapiens

Protein Variants

Protein Variants Comment Organism
additional information residues of CBR3 exchanged to the corresponding amino acids of CBR1. Mutation of nine residues (236-244) in the vicinity of the catalytic center and a proline (P230) in CBR3 to the corresponding residues of CBR1 reveals a much higher kcat/Km value (5.7 micromol/min) towards isatin Homo sapiens
P230W active towards isatin and 9,10-phenanthrenequinone as the wild-type Homo sapiens
V244M inactive towards menadione, active towards isatin and 9,10-phenanthrenequinone as the wild-type Homo sapiens
