The N-formyl-L-tryptophan-chymotrypsin complex in solution

Biochemical and Biophysical Research Communications, 1970
Abstract A high-resolution proton magnetic resonance study of the reversible complex formed between N-formyl- L -tryptophan and the proteolytic enzyme α-chymotrypsin has been carried out.The data indicate that the signals from the aromatic protons of the inhibitor are shifted upfield considerably in the enzyme-inhibitor complex but that the vinyl,

Phosphorylase-catalyzed N-formyl-α-glucosaminylation of maltooligosaccharides

Carbohydrate Research, 2010
This paper describes the phosphorylase-catalyzed enzymatic N-formyl-alpha-glucosaminylation of maltooligosaccharides for direct incorporation of 2-deoxy-2-formamido-alpha-D-glucopyranose units into maltooligosaccharides. When the reaction of 2-deoxy-2-formamido-alpha-D-glucopyranose-1-phosphate (GlcNF-1-P) as the glycosyl donor and maltotetraose as a ...

The role of N-formyl-methionyl-sRNA in protein biosynthesis

Journal of Molecular Biology, 1966
Bacterial sRNA has been fractionated into two methionine-accepting species, only one of which could be formylated. The binding of each charged species to ribosomes under the direction of a variety of trinucleoside diphosphates has been studied. The codeword AUG could be assigned to both species, whereas the related trinucleoside diphosphates GUG and ...

Nucleotide Sequence of N-Formyl-methionyl-transfer RNA

Nature, 1968
N-Formyl-methionyl-transfer RNA is thought to be the chain-initiating tRNA of protein synthesis in bacterial systems. The complete nucleotide sequence of this tRNA from Escherichia coli has now been worked out.

The synthesis and mutagenicity of the N-formyl analog of N-hydroxyphenacetin

Carcinogenesis, 1983
The synthesis and purification of N-hydroxy-N-formyl-p-phenetidine (N-OH-FP) is described. This new compound was subjected to mutagenicity testing using Salmonella typhimurium strains TA98, TA100, TA1535, TA1537 and TA1538 both in the presence and absence of the post-mitochondrial fraction of rat liver homogenate.

Synthesis of Triethyl N-Formyl-N-phosphonomethylglycinate and Diethyl N-Formyl-N-phosphonomethylglycine and Studies of Their Rotational Conformers by Dynamic NMR

Journal of Chemical Research, 1999
Reaction of ethyl N-phosphonomethylglycinate with triethyl orthoformate gave a mixture of triethyl N-formyl-N-phosphonomthylglycinate (3) and diethyl N-formyl-N-phosphonomethylglycine (4), the rotational barriers of which have been investigated theoretically and experimentally.

Synthesis and Stereodynamics of N-Formyl-1,2,3- Selenadiazolopyridines

Phosphorus, Sulfur, and Silicon and the Related Elements, 2012
Abstract The 4,6-diaryl-6,7-dihydro-[1,2,3]selenadiazolo[5,4-c]pyridine-5(4H)-carbalde hydes were synthesized from 2,6-diarylpiperidin-4-ones and characterized using infrared, 1H, 13C Nuclear Magnetic Resonance (NMR), and mass spectroscopic techniques. On the NMR time scale, the compounds exist in syn and anti isomeric forms.

Synthesis of N-formyl dihydropyrazoles as urease inhibitors

Pure and Applied Chemistry
Abstract In this study dihydropyrazole based derivatives were synthesized from substituted chalcone through Michael addition reaction. Urease inhibition activity of the compounds was evaluated, revealing that most compounds exhibited moderate inhibition. Among the synthesized compounds, 2b, 2m, and 2n demonstrated
