Opis:: The stable EPR signal produced by ionizing radiation in crystalline D-mannose (C6H12O6) and separated from cranberries (Vaccinium oxycoccus) was studied. The isothermal heating of irradiated sample at 95°C for 10 minutes (melting point of D-mannose is 132°C) resulted in the modifi cation and simplifi cation of the EPR signal involved. The isotropic quartet has been recognized in the EPR signal of heat-treated sample. Molecular structure of the isotropic quartet identifi ed in the complex EPR signal of D-mannose crystallite is proposed.

Tytuł:: Mannose inhibition of nitrate uptake by wheat roots

Opis:: The effect of mannose on nitrate uptake was investigated by a new non-invasive technique. Under normal condition, nitrate uptake by wheat (Triticum aestivum L.) roots was about 1-7 µmol gfwt-1 h-1. After the addition of 10 mM mannose, net nitrate influx by wheat roots started to decrease and reached a new steady state at -40 ±50% of the control value after 73 min. After mannose supplied for 2 h, its removal caused net nitrate influx to be recovered to an original rate. Therefore, the inhibition of mannose on nitrate uptake is not due to the onset of programmed cell death because it starts too rapidly and it is reversible, however, it is probably due to Pi and consequent ATP depletion.

Opis:: O-glycosylation has been considered a limiting factor in protein secretion in filamentous fungi. Overexpression of the yeast DPM1 gene encoding dolichylphosphate mannose synthase (DPMS) in an Aspergillus nidulans mutant (BWB26A) deficient in O-glycosylation caused an increase in the number of secretory vesicles and changes in protein secretion. However, the secretory proteins, primarily O-mannosylated glucoamylase and N-glycosylated invertase, were mainly trapped in the periplasmic space. Different glycoforms of invertase were found insite the cells, in the periplasmic space and in the cultivation medium. Our data point to the importance of the cell wall as a barrier in protein secretion.

molecular modeling and docking
Opis:: The mannose-binding agglutinin from bulbs of Lycoris aurea (LAA) agglutinates rabbit but not human erythrocytes. The molecular mass of the monomer in SDS/PAGE is 12 kDa while the apparent molecular mass in gel filtration is 48 kDa, indicating that LAA is a homotetramer. The full-length cDNA of LAA contains 683 bp with an open reading frame encoding a protomer of 162 amino-acid residues. Hydrophobic Cluster Analysis and molecular modeling of the 109-residue mature polypeptide suggested a similar secondary and tertiary structure to those of Narcissus pseudonarcissus agglutinin (NPA). Molecular docking revealed that, besides the three mannose-binding sites common among Amaryllidaceae lectins, LAA also contains a fourth unique mannose-binding site formed by a tryptophan cluster. The existence of four mannose-binding sites in each monomer of LAA is very unusual and has only been reported for NPA earlier.

Opis:: Radicals produced by ionizing radiation in sugars, the components of dried and raw fruits give rise to stable multicomponent electron paramagnetic resonance (EPR) signals unidentified so far. The subject of the present EPR study is to identify the radicals stabilized in gamma-irradiated crystalline sugars, D(+)mannose and L(-)sorbose extracted from cranberries (Vaccininum oxycoccos) and rowan berries (Sorbus aucuparia), respectively. EPR measurements and density functional theory (DFT) simulations were employed for that purpose.
