(1) Mannose receptor mediated uptake by the reticuloendothelial system has been suggested as an explanation for the rapid removal of ricin A chain antibody conjugates from the circulation after their administration.
(2) As a group, the three mammalian proteins resemble bovine serum conglutinin and behave as lectins with rather broad sugar specificities directed at certain non-reducing terminal N-acetylglucosamine, mannose, glucose and fucose residues, but with subtle differences in fine specificities.
(3) The intracellular levels of the 6-phosphates of glucose, fructose, and mannose did not increase in the presence of 2-dG.
(4) The expression of both mannose-binding proteins A and C mRNA is restricted to the liver under basal and stress conditions.
(5) (3) What role does the mannose-6-phosphate receptor (M6PR) system play in the delivery of MPO to the lysosome?
(6) This pattern of stimulation suggests that extracts of sec53 cells are deficient in phosphomannomutase activity or in the production of a precursor of mannose 1-phosphate.
(7) Most notable was an average twofold increase in the relative amount of high mannose glycopeptides compared to complex glycopeptides for the leukemic cells.
(8) This result indicates that part of 5'-nucleotidase keeps one or two high-mannose or hybrid chains in the mature form, even after prolonged pulse-chase labeling.
(9) Electron microscopy revealed an absolute correlation between expression of four plasmid-dependent, temperature-inducible properties related to the bacterial surface: (i) a fibrillar matrix covering the outer membrane, (ii) outer membrane protein YOP1, (iii) spontaneous autoagglutination, and (iv) mannose-resistant hemagglutination of guinea pig erythrocytes.
(10) Glycosylated proteins such as HRP, DHRP, and mannosylated bovine serum albumin (M-BSA) are known to bind to mannose receptors (mannosyl-fucosyl receptor [MFR]) on the surface of M phi.
(11) [2-3H]Mannose incorporation into cerebellar glycoproteins was greater in malnourished rats during the period of brain growth spurt than in normally fed rats at all ages studied.
(12) In summary, these studies show: 1) that the H-35 cell IGF-II receptor is synthesized first as a 245-kDa precursor having 4-6 high-mannose oligosaccharide side chains, 2) processing of the receptor oligosaccharides by mannose removal and terminal sialylation converts the 245-kDa precursor to the 250-kDa mature product which has been previously identified as the functional receptor in the plasma membrane, 3) the apparent molecular mass of the receptor in the absence of N-glycosylation is 232-kDa, and 4) glycosylation of the IGF-II receptor is required for the acquisition of IGF-II binding activity.
(13) precursor phaseolin) is incubated with jack bean alpha-mannosidase show that the high mannose glycan on Asn252, but not the one on Asn341, is susceptible to enzyme degradation.
(14) Control experiments with other constructs (e.g., allopurinol riboside linked to the mannose-free polymer) confirmed that the enhancement of activity was indeed achieved by means of the mannose homing device.
(15) In addition other relevant carbohydrate components like ribose, mannose, galactose and glucose can be determined simultaneously.
(16) The O-polysaccharide was found to be a high molecular weight polymer of a repeating pentasaccharide unit composed of D-mannose, D-galactose, L-rhamnose, 2-acetamido-2-deoxy-D-glucose, and 2-acetamido-2,3-dideoxy-3-formamido-D-rhamnose residues (1:1:1:1:1) and had the structure: [formula: see text]
(17) This study demonstrates that extracts of 15B cells, in contrast to the parent cell line, do not transfer N-acetylglucosamine residues from UDP-GlcNAc to certain glycopeptide and glycoprotein acceptors containing terminal nonreducing alpha-linked mannose residues.
(18) Administration of different brain fuels--glucose, mannose, fructose, or the ketone beta-hydroxybutyrate--reduced hippocampal damage induced by coadministration of GCs and either of 2 different neurotoxins (kainic acid and 3-acetylpyridine).
(19) Most of the enzyme produced by cells is secreted into the growth medium and is extensively glycosylated with a series of short O-linked mannose oligosaccharides ranging in size from Man2 to Man5.
(20) The content of high-mannose-type oligosaccharides was comparable to that of the complex type in normal thyroglobulins.

Definition:
(n.) A carbohydrate of the glucose group found in the thickened endosperm of certain seeds, and extracted as yellow sirup having a sweetish-bitter taste.
