The occurrence of the complete orotic acid pathway for the biosynthesis de novo of pyrimidine nucleotides was demonstrated in the intact cells of roots excised from summer squash (Cucurbita pepo L. cv. Early Prolific Straightneck). Evidence that the biosynthesis of pyrimidine nucleotides proceeds via the orotate pathway in C. pepo included: (a) demonstration of the incorporation of [(14)C]NaHCO...

Bu çalışma, S4 kademesinde ümitvar olarak belirlenmiş 105 adet çerezlik kabak hattında (Cucurbita pepo L.), bazı morfolojik özelliklerin incelenmesi ve genotipler arası yakınlıklar belirlenmeye çalışılmıştır. Çalışmada bitki, meyve tohum özelliklerine ait gözlem ölçümler yapılmıştır. Genotiplerin bitki görünümü %81.9 dik, %15.2 sarılıcı, %0.9 yarı sarılıcı bulurken kol atma derecesi %32.3 zayıf...

Oligopeptidases of starter and nonstarter lactic acid bacteria contribute to the proteolytic events important in maturation and flavor development processes in cheese. This paper describes the molecular cloning, expression, and specificity of the oligopeptidase PepO from the probiotic nonstarter strain Lactobacillus rhamnosus HN001 (DR20). The pepO gene encodes a protein of 70.9 kDa, whose prim...

pumpkin, as a dietary plant, has been used in traditional medicine around the world. in addition, during the last decade, antidiabetic, antihypertensive, antitumor, intestinal antiparasitic, antibacterial, anti hypercholesterolemia, anti-inflammatory, immunomodulatory and analgic effects of pumpkin has been reported. the aim of the present study was to determine the effects of different extract...

The capacity of intact cells of roots excised from summer squash plants (Cucurbita pepo L. cv Early Prolific Straightneck) to synthesize purine nucleotides de novo was investigated. Evidence that purine nucleotides are synthesized de novo included: (a) demonstration of the incorporation of [1-(14)C]glycine, [2-(14)C]glycine, NaH(14)CO(3), and H(14)COONa into total adenine nucleotides; (b) obser...
