Glycoprotein Metabolism in the Cotyledons of Pisum sativum during Development and Germination.
The glycoprotein nature of legumin and vicilin, the reserve globulins in the cotyledons of Pisum sativum was studied. Legumin from mature seed was found to contain 1% neutral sugars (mannose and glucose) and 0.1% amino sugar (glucosamine), whereas vicilin contained 0.3% neutral sugar (mannose) and 0.2% amino sugar (glucosamine). On the basis of the incorporation of (14)C-labeled glucosamine, it...
متن کاملSynthesis and Interconversion of Amino Acids in Developing Cotyledons of Pea (Pisum sativum L.).
Freshly isolated cotyledons from 10-day developing pea (Pisum sativum) seeds were fed radiolabeled precursors for 5 hours, and the specific radioactivity of the free and total protein amino acids was determined using a dansylation procedure. When the seven most abundant amino acids in phloem exudate of pea fruits (asparagine, serine, glutamine, homoserine, alanine, aspartate, glycine) were fed ...
متن کاملThe Influence of Axis Removal on Protein Metabolism in Cotyledons of Pisum sativum L.
The protein metabolism of cotyledons attached to the embryonic axis has been compared with that in cotyledons removed from the axis at the initiation of a 6-day imbibition. Total protein declined in the attached but not in the detached cotyledons. Concurrent with the decline in protein level in the intact cotyledons there was an increased capacity to incorporate exogenously supplied leucine int...
متن کاملInhibition of Cuticular Lipid Biosynthesis in Pisum sativum by Thiocarbamates.
Treatment of slices of young pea leaves (Pisum sativum) with muM solutions of alpha-chlorallyl diethyldithiocarbamate, dichloroallyl diisopropylthiocarbamate, or S-ethyldipropylthiocarbamate resulted in inhibition of incorporation of [1-(14)C]acetate into C(31) alkane and C(31) secondary alcohol, very little effect on the synthesis of C(26) and C(28) fatty alcohols, and an accumulation of (14)C...
متن کاملUDP-glucose: glucosyltransferase activity involved in the biosynthesis of flavonol triglucosides in Pisum sativum L. seedlings.
From young, light-grown seedlings of Pisum sativum L. an enzyme activity catalyzing the glucosylation of kaempferol and quercetin in the 3-position to form the 3-0-triglucoside derivative has been demonstrated. The reaction proceeds from the aglycone via the mono- and diglucoside intermediates. The triglucoside can be produced from any of the less substituted derivatives with uridine diphosphat...
