Regulatory helix deletion in glutamate decarboxylase reduces GABA and enhances Agrobacterium-mediated transient expression in lettuce
{{output}}
Gamma-aminobutyric acid (GABA) is a metabolite involved in plant growth and stress responses, with its synthesis regulated by glutamate decarboxylase (GAD). Plant GAD enzymes have an autoinhibitory α-helix at the C-terminus, which calmodulin (CaM) binding typ... ...
