(1993)The digestion of tubulin with subtilisin and the reassociation of the digestion products was followed by means of the fluorescent probe 4',6-diamidino-2-phenylindole (DAPI). The fluorescence spectra of DAPI bound to chicken ...
-
(1993)Microcin E492, a polypeptide antibiotic, has been shown to have an Mr, of 6,000 by urea-SDS-polyacrylamide gel electrophoresis of the fluorescently labelled compound. It is known that the bactericidal action of microcin ...

(1993)2,4-Dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), a hydroxamic acid involved in the resistance of wheat to the aphid Rhopalosiphum padi, and known to react with serine and cysteine residues, inactivated acylcholinesterases ...
-
(1993)1. A single dose of pentazocine induces cross-tolerance the analgesic effects of the kappa agonist U 50488H. Tolerance is observed by means of the hot plate test or by the i.p. administration of acetic acid 6 or 24 hr after ...
-
(1993)We present a comparative study of Escherichia coli with normal and increased amounts of fructose-1,6-bisphosphate aldolase. Most experiments employed a resting cell system involving a high cell density (so as to obtain the ...

(1992)Fusion of Bacillus subtilis plasma membrane vesicles with planar lipid bilayers induced the appearance of discrete current fluctuations characteristic of ion channels. These channels showed a wide range of conductances and ...
-
(1992)Ursolic acid from Jacaranda decurrens showed toxicity and feeding deterrency towards the greenbug Schizaphis graminum. Biological activity was determined by analyzing ursolic acid effects on the survival, reproductive ...

(1992)Using a λgt10 cDNA library obtained from Xenopus laevis oocytes and probes derived from the known sequences of the human and Drosophila genes, a cDNA coding for the α-subunit of the X. laevis casein kinase II was isolated. ...
-
(1992)Polyglutamate analogs of folate and related compounds were tested as inhibitors of casein kinase II (CK II) obtained from Xenopus laevis. The inhibitory capacity of the pteroyl, 4-amino-10-methyl pteroyl (the methotrexate ...
