The beta12-beta13 loop is a key regulatory element for the activity and properties of the catalytic domain of protein phosphatase 1 and 2B.

abstract：:An inert polysaccharide scaffold identified as a 5-15% component of prion rods (PrP 27-30) is unambiguously distinguishable from the N-glycosyl groups and the GPI anchor of PrP, and consists predominantly of 1,4-linked glucose with some branching via 1,4,6-linked glucose. We show that this polysaccharide scaffold is a...
