The beta12-beta13 loop is a key regulatory element for the activity and properties of the catalytic domain of protein phosphatase 1 and 2B
{{output}}
The molecular architectures of the catalytic core of protein phosphatase 1 (PP1) and protein phosphatase 2B (PP2B) are similar, and both contain a beta12-beta13 loop that consists of non-conserved residues. A truncation mutant containing the PP2B catalytic dom... ...
