Abstract
A CMP-sialic acid: GM3 sialyltransferase (GD3 synthase) and a CMP-sialic acid: LacCer sialyltransferas (GM3 synthase) have been purified 10,000- and 3,000-fold, respectively, from the Triton X-100 extract of rat brain. The two enzymes were purified and resolved by affinity chromatography on two successive CDP-Sepharose columns by NaCl gradient elution. Final purification of GD3 synthase was achieved by specific elution from a 'GM3 acid'-Sepharose column with buffer containing GM3. Sodium dodecylsulfate-gel electrophoresis of GD3 synthase revealed a single major protein band with an apparent molecular weight of 55,000.
