| sialometaplasia, necrotizing | A benign, inflammatory, variably ulcerated, occasionally bilateral, self-healing lesion of the minor salivary glands that is often confused clinically and histologically with carcinoma. (12 Dec 1998) |
| sialometry | A measurement of salivary secretion function, generally for a comparison of a denervated or diseased gland with its healthy counterpart. Origin: sialo-+ G. Metron, measure (05 Mar 2000) |
| sialopeptidase | <enzyme> Releases sialic acid-containing peptides from hela cells Registry number: EC 3.4.- (26 Jun 1999) |
| sialophorin | <protein> CD43, (sialophorin) Widely distributed membrane associated mucin, the major sialoglycoprotein of thymocytes and mature T-cells. Transmembrane protein with extensive O linked glycosylation (75-85 oligosaccharides on the 239 residue extracellular domain). Extends at least 45nm beyond plasma membrane. Similar but not homologous to episialin. (18 Nov 1997) |

| sialylparagloboside N-acetylgalactosaminyltransferase | <enzyme> Forms galnac beta1-4(neuac alpha2-3)gal beta1-4glycnac beta1-3gal beta1-4glyc-cer which is found in the stomachs of japanese people; not the same as gm2 synthase Registry number: EC 2.4.1.- Synonym: ngm-1 synthase, udpgalnac-sialylparagloboside n-acetylgalactosaminyltransferase, sialylparagloboside beta1-4 n-acetylgalactosaminyltransferase (26 Jun 1999) |
| sialyltransferases | <enzyme> A group of enzymes with the general formula cmp-n-acetylneuraminate:acceptor n-acetylneuraminyl transferase. They catalyze the transfer of n-acetylneuraminic acid from cmp-n-acetylneuraminic acid to an acceptor, which is usually the terminal sugar residue of an oligosaccharide, a glycoprotein, or a glycolipid.
