Est119
Est119 is an esterase originally identified in the Thermobifida alba strain AHK119. Est119 has been shown to degrade aliphatic-aromatic copolyesters and decrease the size of polymer particles of other biodegradable plastics, with an optimal temperature range of 45-55°C

Figure 1. Michaelis-Menten Esterase Activity Assay of Thermoanaerobacter thermohydrosulfuricus lipase with 4-nitrophenyl butyrate (pNOB). Assays were conducted with 1.5 µM of lipase in PBS with pNOB concentration ranging from 0.0365-0.11 µM. The rate of change of absorbance was monitored at 410 nm for 1 min. A) Wild-type TTL lipase chromogenic assay with initial rate as a function of substrate concentration at 25 B) Wild-type TTL lipase chromogenic assay with initial rate as a function of substrate concentration at 60 ℃ C) TTL lipase chromogenic assay with initial rate as a function of substrate concentration, with norleucine introduced by residue specifically by SPI at 25 ℃ D) TTL lipase chromogenic assay with initial rate as a function of substrate concentration, with norleucine introduced by residue.
