A cDNA encoding acetylcholinesterase (AChE) (EC 3.1.1.7) from Torpedo californica was isolated and from its nucleotide sequence the entire amino acid sequence of the processed protein and a portion of the leader peptide has been deduced. Approximately 70% of the tryptic peptides from the catalytic subunit of the 11 S form have been sequenced, and a comparison of the peptide sequences with the sequence inferred from the cDNA suggests that the cDNA sequence derives from mRNA for the 11 S form of the enzyme. The amino acid sequence is preceded by a hydrophobic leader peptide and contains an open reading frame encoding for 575 amino acids characteristic of a secreted globular protein. Eight cysteines, most of which are disulfide linked, are found along with four potential sites of N-linked glycosylation. The active-site serine is located at residue 200. Local homology is found with other serine hydrolases in the vicinity of the active site, but the enzyme shows striking global homology with the COOH-terminal portion of thyroglobulin. Further comparison of the amino acid sequences of the individual enzyme forms with other cDNA clones that have been isolated should resolve the molecular basis for polymorphism of the AChE species.
