    Notes: Summary The nucleotide sequences of the genes encoding the acetate-inducible glyoxylate cycle enzyme isocitrate lyase from the ascomycete fungi Aspergillus nidulans (acuD) and Neurospora crassa (acu-3) are presented. The respective A. nidulans and N. crassa genes are interrupted at identical positions by two introns and encode proteins of 538 and 543 amino acids, which have 75% identity. The predicted protein sequences do not demonstrate the C-terminal tripeptide S-K-L that has been implicated in peroxisomal targeting and found in the glyoxysomally located enzyme malate synthase from the same species. However, the protein sequences do exhibit a partial repeat which, in common with malate synthase, is located in regions that are absent from, or non-homologous with, the E. coli enzyme, which is not compartmentalized.

    Notes: Abstract The association of thallium acetate ion in 2,2,2-trifluoroethanol and dimethyl-sulfoxide has been investigated by thallium-205 NMR spectroscopy. Analysis of the association constants as a function of temperature indicates that in trifluoroethanol the association enthalpy and entropy are, respectively, 1.6 kcal-mol−1 and 19.3 cal-mol−1-K−1 and in dimethylsulfoxide they are-0.99 kcal-mol−1 and 18.0 cal-mol−1-K−1. Examination of the temperature dependence of the chemical shift of the ion-pair reveals that in dimethylsulfoxide the ion-pair exists as a contact species, while in trifluoroethanol the solvent-separated ion-pair is more likely.
