Studies on a patient with iminopeptiduria. I. Identification of urinary iminopeptides
Abstract:
A patient suffering from recurrent ulcers on the legs was found to excrete large amounts of iminodipeptides in the urine. Among the iminodipeptides excreted, Glu-Hyp, Asp-Pro, Glu-Pro, Leu-Hyp, Gly-Pro, Thr-Pro, Ser-Pro, Ala-Pro, Val-Pro, Ile-Pro, Leu-Pro, and Phe-Pro were identified and their quantities estimated. Some of the iminopeptides had to be synthesized for purposes of identification.
