چکیده
A dimeric form of acetylcholinesterase from Torpedo californica was purified to homogeneity by affinity chromatography subsequent to solubilization with a phosphatidylinositol-specific phospholipase C of bacterial origin. Bipyramidal crystals of the enzyme were obtained from solutions in polyethylene glycol 200. The crystals diffract to 2.0 A (1 A = 0.1 nm) resolution. They were found to be orthorhombic, space group P2221, with a = 163.4(+/- 0.2) A, b = 112.1(+/- 0.2) A, c = 81.3(+/- 0.1) A.

Quantitative solubilization of the phospholipid-associated form of acetylcholinesterase (AChE) from Torpedo electric organ can be achieved in the absence of detergent by treatment with phosphatidylinositol-specific phospholipase C (PIPLC) from Staphylococcus aureus [Futerman, Low & Silman (1983) Neurosci. Lett. 40, 85-89]. The sedimentation coefficient on sucrose gradients of AChE solubilized i...
متن کاملAmalgam, an axon guidance Drosophila adhesion protein belonging to the immunoglobulin superfamily: over-expression, purification and biophysical characterization.
Amalgam, a multi-domain member of the immunoglobulin superfamily, possesses homophilic and heterophilic cell adhesion properties. It is required for axon guidance during Drosophila development in which it interacts with the extracellular domain of the transmembrane protein, neurotactin, to promote adhesion. Amalgam was heterologously expressed in Pichia pastoris, and the secreted protein produc...
متن کاملEctoenzymes of the kidney microvillar membrane. Differential solubilization by detergents can predict a glycosyl-phosphatidylinositol membrane anchor.
The pattern of solubilization of nine kidney microvillar ectoenzymes by a range of detergents distinguished two classes of membrane proteins: those released from the membrane by bacterial phosphatidylinositol-specific phospholipase C and those not so released. The latter group of transmembrane proteins were solubilized efficiently (greater than 80%) by all the detergents examined. In contrast, ...

The structure of the glycan moiety of the glycosyl-phosphatidylinositol (GPI) membrane anchor from Torpedo californica (electric fish) electric-organ acetylcholinesterase was solved using n.m.r., methylation analysis and chemical and enzymic micro-sequencing. Two structures were found to be present: Glc alpha 1-2Man alpha 1-2Man alpha 1-6Man alpha 1-4GlcN alpha 1-6myo-inositol and Glc alpha 1-2...
