The relationship of folic acid to formate metabolism in the rat; formate incorporation into purines.
The considerations which prompted an investigation of the r61e of folic acid in formate metabolism were discussed in an earlier paper (1) in which it was reported that rats deficient in this vitamin incorporated less of a standard dose of CY4-formate into certain amino acids and heme than did rats fed folic acid. There is abundant microbiological evidence to indicate an interrelationship betwee...
متن کاملSelective selC-Independent Selenocysteine Incorporation into Formate Dehydrogenases
The formate dehydrogenases (Fdh) Fdh-O, Fdh-N, and Fdh-H, are the only proteins in Escherichia coli that incorporate selenocysteine at a specific position by decoding a UGA codon. However, an excess of selenium can lead to toxicity through misincorporation of selenocysteine into proteins. To determine whether selenocysteine substitutes for cysteine, we grew Escherichia coli in the presence of e...
متن کاملTHE INCORPORATION OF FORMATE-Cl4 INTO CITROVORUM FACTOR* BY SIGMUND
Jukes (1) and Broquist et al. (2) reported that the addition of formate or serine to incubating cells of an A-Methopterin-resistant strain of Xtreptococcus.faecalis increased the amount of citrovorum factor (CF, folinic acid) which was formed from pteroylglutamic acid (PGA). This finding suggested that ‘Lformate-carbon” was incorporated into the structure of CF. Under appropriate conditions an ...

متن کاملIn vitro incorporation of glycine-2-C14 into purines and proteins.
is advantageous for the in iiitro study of the syn thetic reactions of growing mammalian tissue be cause it provides undamaged mammalian cells whose viability can be tested. In addition, since it is obtained as a suspension of free-living cells, it has the inherent advantages usually available only with microbial cells. With cell suspensions of the Ehnlich ascites-cell carcinoma, the Gardner ly...
