The presence of dipeptide glycylglycine as a -glutamyl acceptor increased the deglutamylation activities of AsGGT1, AsGGT2, and AsGGT3 ( Figure 5 ), showing that these GGTs catalyze transpeptiation more efficiently than hydrolysis, as in GGTs from Arabidopsis and onion (Storozhenko et al., 2002
For the Glow Stack, the gold standard is Bacteriostatic Reconstitution Water (bac)
