This domain is found at the N terminus of Class B High Molecular Weight Penicillin-Binding Proteins. Its function has not been precisely defined, but is strongly implicated in PBP polymerisation. The domain forms a largely disordered 'sugar tongs' structure.	Domain

This domain is found at the C termini of several Penicillin-binding proteins and bacterial serine/threonine kinases [1]. It binds the beta-lactam stem, which implicates it in sensing D-alanyl-D-alanine - the PBP transpeptidase substrate. It is a small globular fold consisting of 3 beta-sheets and an alpha-helix. The name PASTA is derived from PBP and Serine/Threonine kinase Associated domain.	Domain
