Defensive secretions of adult Chlaenius cordicollis (Coleoptera: Carabidae) from Manitoba and Pennsylvania were analyzed across the life cycle in a multi-year study using solid phase microextraction and gas chromatography-mass spectrometry. In concur

We report properties of five active site mutants of Escherichia coli citrate synthase, in which histidine 264, aspartate 362, and phenylalanine 383 were replaced by alanines, and arginines 387 and 407 by leucines. All mutants have much lower turnover

Escherichia coli citrate synthase is strongly and specifically inhibited by NADH, but this inhibition can be prevented by reacting the enzyme with Ellman's reagent. We have now labeled the single reactive cysteine covalently with monobromobimane and

The locus for sorbitol dehydrogenase (SORD, E.C. 1.1.1.14) has been shown to segregate with hexosaminidase A and mannose phosphate isomerase in a series of human-Chinese hamster somatic cell hybrids. Cytogenetic analysis supports the assignment to ch

Human fibroblast cells were exposed to 0, 10, 20, or 40 Grays of gamma rays and then fused with unirradiated Chinese hamster cells deficient in HPRT. THAG selection system was used to ensure that only hybrid cell lines could survive. The time of appe

Several independent human-Chinese hamster hybrid cell lines have been monitored for growth rate and chromosome composition. The rate of growth, as indicated by doubling time during log phase, was positively correlated with the number of human chromos

Summary A reductase specific for aromatic α-keto acids (KAR) is described. It is found in several human tissues, including red cell lysates and fibroblasts. In a population survey, one of 110 red cell lysates tested had a three banded isozyme patter

Samples of the rare SD, FD and ID phenotypes of placental alkaline phosphatase were compared by starch gel electrophoresis and by measuring L-leucine inhibition with the numbered phenotypes of Donald and Robson. The 'D-variant' was found to be identi

The citrate synthases of Gram-negative bacteria, unlike those of eukaryotes, are inhibited allosterically by NADH, but the two kinds of citrate synthase are about 30% homologous in amino acid sequence--the two Gram-negative citrate synthase sequences
