4.1.1.15 | Calmodulin |
a unique feature of plant GAD is the presence of a calmodulin (CaM)-binding domain at its C-terminus. In plants, transient elevation of cytosolic Ca2+ in response to different types of stress is responsible for GAD activation via CaM |

GAD can be regulated in vivo by Ca2+/calmodulin atpH 5.8. The addition of bovine calmodulin and Ca2+ to the reaction mix causes an activation of GAD activity of 32% |

the cofactor of ScGAD is verified to be either pyridoxal 5'-phosphate (PLP) or pyridoxal. The optimal concentration of either cofactor is 50 mg/l. GAD requires a coenzyme for activity while inactive apo-GAD forms a GAD-PLP complex (holo-GAD) to obtain its activity |
