ABSTRACT:
A .beta.-galactoside-.alpha.-2,6-sialyltransferase derived from a microorganism belonging to the genus Photobacterium has ben disclosed, having the following physicochemical properties:
(1) action and specificity: transferring sialic acid from cytidine monophosphate-sialic acid to the 6-position of a galactose residue in a sugar chain of a glycoconjugate or in a free sugar chain, or to the 6-position of a monosaccharide having a hydroxyl group on carbon at the 6-position and being capable of forming a glycoconjugate.
(2) optimum pH: 5 to 6;
(3) optimum temperature: 30.degree. C.; and
(4) molecular weight: 64,000.+-.5,000 (determined by gel filtration).
