Table 1 Known functional residues comparison of GGT-family: Comparative functional residues of GGT-family proteins are identified through multiple sequence alignment of GGT proteins sequences (Additional file 1)

From: “Phylogenetic and evolutionary analysis of functional divergence among Gamma glutamyl transpeptidase (GGT) subfamilies”

  1. The conserved residues throughout the family are highlighted by green color. Residues highligted with * are part of the lid loop known to be responsible for the transpeptidase activity. Residues represented by ** are proposed acceptor sites binding residues known for GGT transpeptidase activity
