Recombinant Human Acyl-Protein Thioesterase 1/APT-1 is produced with our E. coli expression system. The target protein is expressed with sequence (Met1-Asp230) of Human APT-1 fused with a His tag at the N-terminus. Acyl-Protein Thioesterase 1 (APT-1) is lysophospholipase that belongs to the AB hydrolase 2 family. APT-1 performs on biological membranes to regulate the multifunctional lysophospholipids. It hydrolyzes fatty acids from S-acylated cysteine residues in proteins such as trimeric G α proteins or HRAS, in addition, it also has depalmitoylating activity and low lysophospholipase activity.
