Abstract
Two forms of NAD+-isocitrate dehydrogenase, named ICDH-1 and ICDH-2, have been identified and purified in Phycomyces blakesleeanus NRRL-1555(-). These enzymes forms may be separated by chromatography on DEAE-Sephacel. ICDH-2 induction was a response to the adaptation of Phycomyes growth on acetate as the carbon source. Both enzyme forms were octamers of 388 + or - 30 kDa with apparently identical subunits of 40.5 +/- 5 kDa, but they were distinguishable by their electrophoretic mobilities on polyacrylamide gel electrophoresis. Isoelectric pH values were 5.28 and 4.96 for ICDH-1 and ICDH-2, respectively. ICDH-2 was more stable to urea denaturation than ICDH-1. At pH 7.6, ICDH-1 showed a markedly sigmoidal kinetic behavior with respect to isocitrate. However, ICDH-1 and ICDH-2 showed hyperbolic kinetics with respect to NAD+. THe tribasic form of isocitrate (I3-) and its magnesium complex (MI-) are the true substrates for both enzyme forms. Kinetic data obtained with Mg2+ as a divalent cation for both enzyme forms are compatible with the kinetic mechanism proposed by Cohen and Colman (1974) [Eur. J. Biochem. 47, 35-45] but assuming some degree of interaction between binding sites for the active form of isocitrate. This report describes for the first time the existence of two forms of NAD+-isocitrate dehydrogenase in filamentous fungi. From the changes in activity levels for each form, during adaptation of Phycomyces to growth on acetate and taking into account the kinetic and regulatory properties of both enzyme forms, we discuss the role of ICDH-1 and ICDH-2 in the control of isocitrate flux in Phycomyces.

Abstract
The interactions of urea, trimethylamine-N-oxide (TMAO), and related solutes on a number of enzymes were examined. Urea inhibited enzymatic activity and accelerated the thermal inactivation of catalase, whereas TMAO activated some enzymes but inhibited others. The effects of urea and of TMAO, whether parallel or in opposition, were exerted independently. Thus, in those cases where TMAO increases enzymatic activity, it did so to the same relative degree, whether or not urea was present. TMAO markedly decreased the rate of thermal inactivation of catalase, indicating that it does favor compact protein structures. The assumption that TMAO factors compaction of protein structure, whereas urea has the contrary effect, does not lead to the expectation that TMAO must always oppose the effect of urea on enzymatic activity, since the most compact form of an enzyme may not always be the most active form.

Abstract
The regulation of mitochondrial citrate metabolism has been investigated in oleaginous and non-oleaginous yeasts to ascertain its importance in controlling the rate of citrate efflux from mitochondria. The following observations were made: 1. Citrate efflux from mitochondria of the oleaginous yeast Candida curvata D, in the presence of L-malate and pyruvate, was stimulated by adding ATP and reduced by AMP. In the non-oleaginous yeast, Candida utilis 359, there was very little stimulation of citrate efflux by ATP but it was reduced by AMP. These effects appeared to be generalized as similar results were obtained in an examination of eight further yeasts (seven oleaginous and one non-oleaginous). 2. The effects of ATP and AMP were not observed in mitochondria whose metabolism had been inhibited by antimycin A and rotenone indicating the direct regulation of the citrate translocase was not involved. 3. In C. curvata D, ATP increased the total mitochondrial citrate content and reduced that of 2-oxoglutarate whereas AMP had the reverse effect. In C. utilis 359, AMP had a similar effect but that of ATP was much smaller. 4. To explain these observations the mitochondrial NAD+-dependent isocitrate dehydrogenase was studied in a number of yeasts. The enzyme from oleaginous yeasts had a requirement for AMP for activity and was inhibited by ATP. In non-oleaginous yeasts the enzyme was active in the absence of AMP and increased in activity as the isocitrate concentration increased. 5. The enzyme in C. curvata D was constantly more sensitive to increasing energy charge than that of the non-oleaginous yeast. These results indicate that the supply of citrate (and hence acetyl-CoA) to the cytosol is controlled by the activity of the intramitochondrial NAD+-dependent isocitrate dehydrogenase which in turn is regulated by adenine nucleotides. The sensitivity of this enzyme to the ATP/AMP ratio during lipogenesis is therefore an important control in the accumulation of lipid by yeasts.

Abstract
Addition of acetate to a stationary phase culture of Escherichia coli in glycerol mineral salts medium containing phosphorus-32-labeled orthophosphate results in rapid loss of isocitrate dehydrogenase activity and concomitant incorporation of phosphorus-32 into the enzyme. This is the first example of protein phosphorylation in a bacterium in which the endogenous substrate for the protein kinase has been identified.

Abstract
Two isoenzymes of NADP-linked isocitrate dehydrogenase have been identified in Acinetobacter lwoffi and have been termed isoenzyme-I and isoenzyme-II. The isoenzymes may be separated by ion-exchange chromatography on DEAE-cellulose, by gel filtration on Sephadex G-200, or by zonal ultracentrifugation in a sucrose gradient. Low concentrations of glyoxylate or pyruvate effect considerable stimulation of the activity of isoenzyme-II. The isoenzymes also differ in pH-dependence of activity, kinetic parameters, stability to heat or urea and molecular size. Whereas isoenzyme-I resembles the NADP-linked isocitrate dehydrogenases from other organisms in having a molecular weight under 100000, isoenzyme-II is a much larger enzyme (molecular weight around 300000) resembling the NAD-linked isocitrate dehydrogenases of higher organisms.

Abstract
1. The effect of pH on the V(max.) and concentration of NAD(+) at half-maximum velocity at a constant isocitrate concentration was examined, and the results were related to the requirements for binding of H(+) ions to the enzyme. 2. The effect of varying the NAD(+) concentration on the pH optimum with constant isocitrate concentration was studied. 3. A comparison has been made between the effect of isocitrate concentration on the characteristics of binding of NAD(+) and the effect of NAD(+) concentration on the characteristics of isocitrate binding at three different pH values. 4. The mechanistic and metabolic significance of these studies is considered.
