| murein transglycosylase | <enzyme> Converts glycosidic bond between n-acetylmuramic acid and n-acetylglucosamine into an internal 1-6 anhydro n-acetylmuramyl (hemiacetal) bond in an intramolecular transglycosylation reaction Registry number: EC 2.4.99.- Synonym: murein-murein-6-muramyltransferase (internal cyclizing), soluble lytic transglycosylase, mlt transglycosylase, membrane-bound lytic transglycosylase, lambda r transglycosylase, mltb gene product, slt35 protein, 35-kD soluble lytic transglycosylase (26 Jun 1999) |
| mureins | Peptidoglycans composing the sacculus or cell casing of bacteria, consisting of linear polysaccharides of alternating N-acetyl-d-glucosamine and N-acetylmuramic acid units, to the lactate side chains of which are linked oligopeptides; independent chains are cross-linked in three dimensions via the peptides or the 6-OH groups (the latter may be linked via phosphate to a teichoic acid). Origin: L. Murus, wall (05 Mar 2000) |

| muriate | <chemistry> A salt of muriatic hydrochloric acid; a chloride; as, muriate of ammonia. This term, as also the word muriatic, was formerly applied to the chlorides before their true composition was understood, and while they were erroneously supposed to be compounds of an acid with an oxide. Muriate and muriatic are still occasionally used as commercial terms, but are obsolete in scientific language. See: Muriatic. Source: Websters Dictionary (01 Mar 1998) |
