Nutrition of "Glossina morsitans" : metabolism of U-14C threonine during pregnancy
Following injection of U-]4C threonine into the haemolymph of adult female Glossina morsitans during late pregnancy, radioactivity was detected in the postparturient female and in its offspring, in threonine, lipids, and a range of non¬ essential amino acids. The level of radioactivity recovered from the larva was higher than that remaining in the injected adult, and the radioactivity recovered...
متن کاملEnzymatic Breakdown of Threonine by Threonine Aldolase
1. The enzyme which splits threonine to acetaldehyde and glycine has been partially purified from rat liver (five- to sixfold purification) and the name threonine aldolase proposed for it. 2. The general properties of threonine aldolase have been studied. The enzyme is unstable to a pH below 5. The pH optimum of the enzyme reaction is at 7.5-7.7. The initial rate of production of acetaldehyde i...
متن کاملThe influence of nutrition on the serine and threonine deaminases of microorganisms.
Studies concerning the identity of the serine and threonine deaminases have been carried out in several laboratories. Wood and Gunsalus (1949) employing a partially purified system extracted from Escherichia coli suggested that both serine and threonine are deaminated by the same enzyme. Similarly, studies with Neurospora indicate that these amino acids are deaminated by one enzyme (Yanofsky, 1...

متن کاملRefolding of bovine threonine-neochymotrypsinogen.
The mixed disulfide derivative of fully reduced neochymotrypsinogen was refolded at pH 9.2 and 4 degrees C with 4 mM cysteine as the disulfide interchange catalyst. The yield of regenerated neochymotrypsinogen was 25%; the corresponding yield of refolded chymotrypsinogen was 50%. The refolded neochymotrypsinogen exhibited the characteristics of the native molecule as determined from polyacrylam...
