Intestinal Dipeptidases

Scandinavian Journal of Gastroenterology, 1968
Human intestinal juice, collected at different levels by transintestinal intubation technique, has been studied in respect to its dipeptidase activities, using L-alanyl-L-glutamic acid, L-alanyl-L-proline and glycyl-L-leucine as substrates. Only L-alanyl-L-proline dipeptidase activity was generally observed in samples from the jejunal region.

Intestinal dipeptidases II. Distribution of dipeptidases in the small intestine of the pig

Biochimica Et Biophysica Acta: BBA Enzymology and Biological Oxidation, 1965
Summary 1. A study has been made of the distribution of L -alanyl- L -glutamic acid dipeptidase, glycylglycine dipeptidase (EC 3.4.3.1), glycyl- L -leucine dipeptidase (E.C 3.4.3.2) and glycyl- L -valine dipeptidase along the small intestine of adult pig. 2.

Dipeptidase Activity of Brain

Nature, 1960
AVAILABLE knowledge on the dipeptidase activity of brain is limited to the enzymatic hydrolysis of DL-alanyl-glycine1–3. Detailed studies by Pope et al. have dealt with the intralaminar distribution of dipeptidase activity towards DL-alanyl-glycine in the cerebral cortex of rat1,2 and man3.

Determination of Dipeptidase Activities

Nature, 1964
INVESTIGATIONS of intestinal mucosal dipeptidases have been hampered in the past by the lack of suitable assay methods. The methods in use at present1 require relatively large amounts of substrate and are inadequate for the examination of dipeptidase activities in crude tissue extracts or partially purified preparations.

Correlation between dipeptidase activity and concentration of human liver dipeptidase in serum

Clinica Chimica Acta, 1980
Abstract We describe the relationship between serum enzyme activity and concentration of human liver dipeptidase (HLD) by radioimmunoassay. Using the technique of differential centrifugation, it was found that dipeptidase was predominantly localized in the cytoplasmic fraction of human liver cells.

Renal dipeptidase: Localization and inhibition

Biochimica et Biophysica Acta (BBA) - Enzymology, 1971
Abstract The principle locus of porcine renal dipeptidase activity has been found to be the microsomal fraction of kidney cortex. When the microsomal preparation was incubated with the enzymes, chymotrypsin, trypsin, lipase, and ribonuclease, the peptidase was released to no greater degree than other protein components of this fraction.

Intestinal Dipeptidases: Dipeptidase Activity in the Mucosa of the Gastrointestinal Tract of the Adult Human

Acta Physiologica Scandinavica, 1966
Five dipeptidase activities in the mucosa of the gastrointestinal tract from 25 patients between 22 and 80 years of age were determined. The influence of pH and bivalent metal ions on the various activities was studied. Equally low activities were found in the stomach and the large intestine.

Genetic control of dipeptidase in the Triticeae

Theoretical and Applied Genetics, 1987
Isoelectric focusing has been employed to elucidate the genetic control of a series of dipeptidase isozymes in wheat and its relatives. The phenotype of wheat shows four bands, three of which are shown by aneuploid analysis to be controlled by the loci Dip-A1, Dip-B1 and Dip-D1 on chromosome arms 6AL, 6BL and 6DL, respectively.
