A sensitive assay for beta-ureidopropionase based on derivatization of the reaction product beta-alanine with phenylisothiocyanate has been developed. Purification of the resulting phenylthiocarbamoyl-beta-alanine is achieved on a LiChrospher 100 C18 reversed-phase high-performance liquid chromatography column using an isocratic elution system.
Improved colorimetric procedure for quantitating N-carbamoyl-beta-alanine with minimum dihydrouracil interference.

To evaluate the significance of inborn metabolic disorders of the pyrimidine degradation pathway, 450 children with unspecific neurological symptoms were comprehensively studied; 200 healthy children were recruited as controls. Uracil and thymine as well as their degradation products in urine
A radiochemical assay was developed to measure the activity of beta-ureidopropionase in human liver homogenates which is based on the detection of the reaction product (14)CO(2) by liquid scintillation counting. Radiolabeled N-carbamyl-beta-alanine was prepared within 15 min by a simple
