Glycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...
متن کاملOligosaccharide Specificities of Phaseolus vulgaris
The structural determinants required for interaction of oligosaccharides with leukoagglutinating phytohemagglutinin (L-PHA) and erythroagglutinating phytohemagglutinin (E-PHA) from Phaseolus vulgaris have been studied by immobilized lectin affinity chromatography. Homogeneous oligosaccharides of known structure, purified following release from Asn with Nglycanase and reduction with NaBH4, were ...
متن کاملUromyces phaseoli and Phaseolus vulgaris
To study the function of bean rust haustoria either the host, Phaseolus vulgaris, or the parasite, Uromyces phaseoli, were labeled with 3H-lysine. 24h and 48 h after inoculation samples of the infected leaves were taken and processed for electronmicroscopic autoradiography. When the host was labeled, silver grain densities over the structures of host and parasite were compared. Very low grain d...
متن کاملFactors Affecting Root Formation of Phaseolus Vulgaris.
The successful rootingof leafy cuttings inivolves three physiologieally distinct processes: initiation of root primordia; development of true roots from these initials; and mainitenance of the cutting as ani excised organ during the rooting. The first of these, where it does niot take place sponitanieously, cani be brought about in many plants by treatment with auxini. The second (outgrow^th of...
متن کاملMethylammonium Transport in Phaseolus vulgaris Leaf Slices.
Methylammonium (as a nonmetabolized analog of ammonium) transport was studied in leaf slices of Phaseolus vulgaris L. var. ;Hawkesbury Wonder.' The relationship of influx to external pH (6.0-10.5) shows that the influx at low external pH is a larger fraction of that at high external pH than would be expected from the pK(alpha) of methylammonium and the assumption that only CH(3)NH(2) is enterin...
