Protein Variants

Protein Variants Comment Organism
additional information expression of truncated forms lacking the C-terminal, LIM and/or calponin homology CH regions. The CH, LIM and C-terminal regions lead to an increase of KmNADPH. The C-terminus also determines an about 10fold decrease of kcat Homo sapiens
