Allantoate hydrolysis by allantoate amidohydrolase

Archives of Biochemistry and Biophysics, 1970
Abstract The degradation of allantoate by allantoate amidohydrolase from Streptococcus allantoicus resulted in the production of 1 mole of carbon dioxide, 2 moles of NH 3 , and probably 1 mole of (−)-ureidoglycolate per mole of allantoate. Ureidoglycine was an intermediate and presumably also a substrate for allantoate amidohydrolase.

Enzymic Degradation of Allantoate in Developing Soybeans [PDF]

open access: yesPlant Physiology, 1985
A Mn(2+)-dependent enzymic breakdown of allantoate has been detected in crude and partially purified extracts of developing soybeans. The products detected were CO(2), NH(3), glyoxylate, labile glyoxylate derivatives, and low levels of urea. Urea is initially produced at less than 10% the rate of urease-independent CO(2) release indicating that the ...

Allantoate transport in Saccharomyces cerevisiae [PDF]

open access: yesJournal of Bacteriology, 1979
Allantoate uptake appears to be mediated by an energy-dependent active transport system with an apparent Michaelis constant of about 50 microM. Cells were able to accumulate allantoate to greater than 3,000 times the extracellular concentration. The rate of accumulation was maximum at pH 5.7 to 5.8.

Catabolism of allantoate and ureidoglycolate in Rana esculenta

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. The activities of allantoicase and ureidoglycolase in frog ( Rana esculenta ) liver and kidney extracts were determined. Allantoate amidohydrolase was not involved in allantoate catabolism in frog liver and kidney. 2. 2. Allantoate was converted to urea and (−)-ureidoglycolate by allantoicase and ureidoglycolate was further ...

Allantoate and ureidoglycolate degradation by Pseudomonas aeruginosa

Biochimica Et Biophysica Acta - Biomembranes, 1967
Abstract 1. 1.|A single enzyme, allantoicase (allantoate amidinohydrolase, EC 3.5.3.4), catalyzes the conversion of allantoate to (−)-ureidoglycolate. On the other hand, two enzymes were found to be responsible for the degradation of ureidoglycolate by Pseudomonas aeruginosa extracts: allantoicase, which degraded (+)-ureidoglycolate by 3–4 times ...

Asparagine and Boric Acid Cause Allantoate Accumulation in Soybean Leaves by Inhibiting Manganese-Dependent Allantoate Amidohydrolase [PDF]

open access: yesPlant Physiology, 1992
Our previous work demonstrated substantial accumulation of allantoate in leaf tissue of nodulated soybeans (Glycine max L. Merr., cv Williams) in response to nitrogen fertilization. Research was continued to determine the effect of nitrate and asparagine on ureide assimilation in soybean leaves.
