The action of Pseudomonas fluorescens extracts on asparagine and asparagine derivatives
Biochimica et Biophysica Acta, 1960Abstract Cell-free extracts from Pseudomonas fluorescens hydrolyzed L - and D -asparagine, L - and D -β-aspartohydroxamic acid and α-N-alkyl derivatives of DL -asparagine, but failed to attack L - and D -N-(β-aspartyl)-alkylamines. The extracts also catalyze the formation of β-aspartohydroxamic acid from L - or D -asparagine and ...

Configuration of the Peptide Link and of Asparagine in Glycyl-L-Asparagine
Nature, 1952SINCE the geometrical problem of protein structure is mainly that of the configuration of the polypeptide chains, the geometry of the peptide link itself is a matter of prime importance. However, very few crystal-structure data have yet been published from which precise dimensions of the peptide link may be derived. We have recently carried out a three-

Catalytic deamination of asparagine
Experientia, 1970Es wird die katalytische Deaminierung des Asparagins mittels Cu++ bei 80°–100°C beschrieben. In diesem Temperaturbereich findet die Reaktion auch in Losungen statt, wahrend die Katalyse im Trockenruckstand bedeutend starker ist. Die optimale Konzentration des Cu++ (bezogen auf das Asparagin) ist 1∶4M.

Asparagine is synthesized from glutamine by the reaction of asparagine synthetase (AS) and is the major nitrogen form in both xylem and phloem sap in rice (Oryza sativa L.). There are two genes encoding AS, OsAS1 and OsAS2, in rice, but the functions of individual AS isoenzymes are largely unknown. Cell type- and NH4(+)-inducible expression of OsAS1 as

Structure of Asparagine Monohydrate
Nature, 1961THE structure of asparagine has been discussed several times during recent years1–5. A number of properties would be better explained by a ring structure than by the conventional straight-chain structure1,2, but on the other hand, the carboxylic group had to be free3.

The action of mammalian liver enzyme preparations on asparagine and asparagine derivatives
Biochimica et Biophysica Acta, 1960Abstract α-N-alkyl derivatives of DL -asparagine were not hydrolyzed by rat-liver asparaginase or guinea pig-liver asparaginase. They markedly inhibited the action of these enzymes on L -asparagine. In all cases tested the inhibition was found to be competitive. Rat and guinea pig liver asparaginase did not hydrolyze N-(β- DL -aspartyl)-alkylamines

Production of l-asparagine by tumor cells and the effect of asparagine analogs
Biochemical Pharmacology, 1972Abstract A rapid assay of the ability of intact cells (10–50 mg) to synthesize l -asparagine and l -aspartic acid, and its application to the evaluation of potential asparagine analogs has been devised. Washed cell preparations were incubated at 37° in Eagle's medium (supplemented with l -glutamine, 2 mM, and l -aspartic acid, 0.05 mM), and the ...
