| Y224D mutant at 2.3 A resolution. Mutation results in a change in the conformation of the flexible loop B, including the V-shaped groove | Mus musculus |
| Protein Variants | Comment | Organism |
|---|---|---|
| Q222N | mutation of residue involved in forming the safety belt for binding of the coenzyme. Kinetic constants for 3-hydroxy/3-ketosteroids and 17-hydroxy/ketosteroids similar to wild type | Mus musculus |
| Y224D | mutation reduces the Km value for NADP(H) by up to 80fold and completely reverses the 17alpha stereospecificity of the enzyme | Mus musculus |
| Y224F | mutation of residue involved in forming the safety belt for binding of the coenzyme. Kinetic constants for 3-hydroxy/3-ketosteroids and 17-hydroxy/ketosteroids similar to wild type | Mus musculus |
