| oligoglucan-branching glycosyltransferase | A glucosyltransferase that transfers an alpha-glucosyl residue in a 1,4-alpha-glucan to the primary hydroxyl group of glucose in a 1,4-alpha-glucan. See: 1,4-alpha-d-glucan branching enzyme. Synonym: oligoglucan-branching glycosyltransferase. (05 Mar 2000) |

| asparagine-N-glycosyltransferase | <enzyme> Involved in glycoprotein biosynthesis Registry number: EC 2.4.1.- (26 Jun 1999) |
| macrolide glycosyltransferase | <enzyme> From streptomyces lividans; utilises udp-glucose as cofactor; substrates include macrolides with 12-, 14-, 15-, or 16-atom cyclic polyketide lactones; enzyme specific for the 2'-oh group of saccharide moieties attached to c-5 of the 16-atom lactone ring Registry number: EC 2.4.1.- Synonym: macrolide glucosyltransferase (26 Jun 1999) |
| glycoprotein glycosyltransferase | <enzyme> Enzymes which add monosaccharides from nucleoside mono-or diphosphate monosaccharides onto glycoproteins Registry number: EC 2.4.1.- (26 Jun 1999) |
| glycosyltransferase | <enzyme> Enzymes that catalyze the transfer of glycosyl group to an acceptor. Most often another carbohydrate molecule acts as an acceptor, but inorganic phosphate can also act as an acceptor, such as in the case of phosphorylases. Some of the enzymes in this group also catalyze hydrolysis, which can be regarded as transfer of a glycosyl group from the donor to water. Subclasses include the hexosyltransferases, pentosyltransferases, sialyltransferases, and those transferring other glycosyl groups. Registry number: EC 2.4 Synonym: transglycosylase. (08 Mar 2000) |
| dextrin glycosyltransferase | Dextrin transglycosylase or glycosyltransferase;a 4-glycosyltransferase converting maltodextrins into amylose and glucose by transferring parts of 1,4-glucan chains to new 4-positions on glucose or other 1,4-glucans. Synonym: amylomaltase, D enzyme, dextrin glycosyltransferase, dextrin transglycosylase, disproportionating enzyme. (05 Mar 2000) |
| branching | The act or state of separation into branches; division into branches; a division or branch. "The sciences, with their numerous branchings." (L. Watts) Source: Websters Dictionary (01 Mar 1998) |
| branching enzyme | 1,4-alpha-d-glucan branching enzyme |
| branching factor | 1,4-alpha-glucan-branching enzyme. (05 Mar 2000) |
| branching ratio | <radiobiology> In a fusion reaction involving two nuclei, there are typically a variety of possible sets of products which can form. The branching ratio for a particular set of products is the probability that that set of products will be produced. (09 Oct 1997) |
| false branching | <microbiology> In bacteriology, the appearance of branching produced when a cell is pushed out of the general line of growth and develops a new line of growth while the remaining cells continue to develop along the original line of growth. (05 Mar 2000) |
| 1,4-alpha-glucan branching enzyme | <enzyme> In glycogen or amylopectin synthesis, the enzyme that catalyses the transfer of a segment of a 1,4-alpha-glucan chain to a primary hydroxy group in a similar glucan chain. Chemical name: 1,4-alpha-D-Glucan:1,4-alpha-D-glucan 6-alpha-D-(1,4-alpha-D-glucano)-transferase Registry number: EC 2.4.1.18 (12 Dec 1998) |
