Miscellaneousi

Miscellaneous

Synapses usually contain asymmetric molecules of cholinesterase, with a collagen-like part disulfide-bonded to the catalytic part. A different, globular type of cholinesterase occurs on the outer surfaces of cell membranes, including those of erythrocytes.
This is the catalytic subunit of an asymmetric or soluble form of ACHE.
