Alpha and Omega Classification of β-Lactamase/Transpeptidase-like Superfamily Proteins Based on the Comparison of Their Structural Catalytic Cores
β-Lactamase/transpeptidase-like superfamily proteins are serine proteases that use the Ser–Lys catalytic dyad to carry out their biological functions. Here, we investigate the three known families of β-lactamase/transpeptidase-like superfamily proteins, β-lactamase/D-Ala carboxypeptidase, glutaminas...

| Summary: | β-Lactamase/transpeptidase-like superfamily proteins are serine proteases that use the Ser–Lys catalytic dyad to carry out their biological functions. Here, we investigate the three known families of β-lactamase/transpeptidase-like superfamily proteins, β-lactamase/D-Ala carboxypeptidase, glutaminase, and Dac-like, and describe the structural catalytic cores that govern the catalytic residues in these proteins. We show that the structural catalytic core of these proteins is a combination of three zones, the mutual three-dimensional arrangement of which correspondingly determines their belonging to one of seven and twenty-four established groups and subgroups. |
