The decarboxylation of L-phenylalanine by Streptococcus faecalis R.
Gale (1) and Epps (2) have reported the properties of an enzyme obtained from various strains of Streptococcus faecalis which decarboxylates tyrosine and dihydroxyphenylalanine. Both of these authors reported that the enzyme preparations, whether made by washing the whole organism, by drying the cells with acetone, or by further purification procedures, were specific to the above two amino acid...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولPhospholipids of Streptococcus faecalis.
Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
متن کامل2-ketogluconate Fermentation by Streptococcus Faecalis.
Goddard, J. L. (University of Oklahoma School of Medicine, Oklahoma City), and J. R. Sokatch. 2-Ketogluconate fermentation by Streptococcus faecalis. J. Bacteriol. 87:844-851. 1964.-Streptococcus faecalis 10Cl did not grow with 2-ketogluconate alone as an energy source, but did grow when gluconate was added. More growth was obtained than could be accounted for by the gluconate alone. The requir...
متن کاملAssay of L-phenylalanine as phenylethylamine after enzymatic decarboxylation; application to isotopic studies.
Procedures have been reported for the use of specific bacterial decarboxylases to assay individual amino acids by measurement of the CO2 evolved (1). Since 1 mole of amine is formed for each mole of amino acid decarboxylated, it should also be possible to estimate the amount of amino acid from the quantity of amine formed. When L-phenylalanine is decarboxylated by L-phenylalanine decarboxylase,...
