Constituents of Acetylcholinesterase
1978Constitutents of acetylcholinesterase (AChE; EC 3.1.1.7) amino acids and carbohydrates were determined from highly purified enzyme. AChE was prepared from the electric organ of Torpedo marmorata. For transportation and storage the dissected organs were deep frozen at -30°. Even after a year we could not detect any loss of enzyme activity.

Stereospecificity of erythrocyte acetylcholinesterase
Archives of Biochemistry and Biophysics, 1964Abstract Lactoylcholine is a choline ester which contains an asymmetric carbon atom in the acid portion of the molecule. A study of the hydrolytic rate of the enantiomers of this choline ester by human erythrocyte acetylcholinesterase revealed that the l (+) isomer is hydrolyzed at least four times greater than the d (−) isomer.

ACETYLCHOLINESTERASE IN BULL SPERMATOZOA [PDF]
Reproduction, 1964 Acetylcholinesterase occurs in the head, midpiece and tail fractions of sonically disrupted bull epididymal spermatozoa. The enzyme exhibits the characteristic substrate concentration optimum; 1\m=.\5X 10-5 m-eserine competitively inhibits the hydrolysis of the acetylcholine.

Structure and Function of Acetylcholinesterase
1969Publisher Summary This chapter discusses the structure and function of the enzyme acetylcholinesterase (ACh-ase). The enzyme is a dimer, each protomer comprising two nonidentical chains. The nonidentity of the two groups of polypeptide chains is supported by the determination of the number of active sites of ACh-ase.
