Erythritol Metabolism by Propionibacterium pentosaceum
Randomly labeled erythritol-14C has been synthesized and incubated with fluoride-poisoned suspensions of dried cells of Propionibacterium pentosoceum. Therefrom labeled glycerol-d-P, glyceric acid-j-P, erythritol-l-P, ribose-5-P, xyhalose-5-P, glucose-6-P, fructosed-P, mannosed-P, fructose-1 ,6-di-P, and sedoheptulose-7-P were isolated. Erythritol-W-1-P accumulated more rapidly than did the oth...
متن کاملPurification and properties of D-arabinokinase from Propionibacterium pentosaceum.
Reports on the bacterial utilization of u-arabinose have shown two pathways of dissimilation. The first, reported by Cohen (l), demonstrated that Escherichia coli first isomerized n-arabinose to n-ribulose, which was then phosphorylated. A later report by Doudoroff et al. (2) showed that Pseudomonas saccharophi&a oxidized n-arabinose to n-arabonolactone, which was subsequently hydrolyzed to the...
متن کاملPurification and properties of cobamide coenzymes obtained from Propionibacterium arabinosum.
Propionibacterium arabinosum is known to produce an adeninylcobamide when grown in a medium containing yeast extract or corn steep-liquor (I, 2). Such a medium, although not intentionally fortified with a heterocyclic base, undoubtedly contains substantial amounts of adenine or its derivatives. Addition of an appropriate benzimidazole, purine, or other heterocyclic base to the medium, or to a s...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولA biotin function in succinic acid decarboxylation by Propionibacterium pentosaceum.
Through the demonstration of the importance of biotin to oleic acid synthesis, to oxalacetate decarboxylation and carbon dioxide fixation, and to certain amino acid deamination reactions, as reviewed by Stokstad and Jukes (1949), and to citrulline synthesis (MacLeod et at., 1949), it is becoming increasingly apparent that the coenzyme form of this vitamin may be concerned in many different type...
