Effect of protein kinase a activity on the association of ADP-ribosylation factor 1 to Golgi membranes
(The American Society for Biochemistry and Molecular Biology, 2000)
The small GTP-binding protein ADP-ribosylation factor 1 (ARF1) is an essential component of the molecular machinery that catalyzes the formation of membranebound transport intermediates. By using an in vitro assay that ...

The Emp24 complex recruits a specific cargo molecule into endoplasmic reticulum-derived vesicles
(Rockefeller University Press, 2000)
Members of the yeast p24 family, including Emp24p and Erv25p, form a heteromeric complex re- quired for the efficient transport of selected proteins from the endoplasmic reticulum (ER) to the Golgi ap- paratus. The ...

Isolation, characterization and antitumour properties of the 1,2-propylenediaminetetraacetate-trans-diaqua-copper(II)
(Hindawi Publishing Corporation, 2000)
A trans-diaquacomplex formed by copper(II) sulphate and the sequestering polyamminopolycarboxylic ligand 1,2-propylenediaminetetraacetic acid (PDTA) has been isolated and characterized by chemical analysis, titrimetry, ...

A purL mutant of Sinorhizobium fredii HH103 is symbiotically defective and altered in its lipopolysaccharide
(Microbiology Society, 2003)
The pleiotropic phenotype of an auxotrophic purL mutant (SVQ295) of Sinorhizobium fredii HH103 has been investigated. SVQ295 forms colonies that are translucent, produce more slime and absorb less Congo red than those ...

Anti-tumour activity of Digitalis purpurea L. subsp. heywoodii
(Georg Thieme Verlag, 2003)
Recent research has shown the anticancer effects of digitalis compounds suggesting their possible use in medical oncology. Four extracts obtained from the leaves of Digitalis purpurea subsp. heywoodii have been assessed ...

A gibberellin-induced nuclease is localized in the nucleus of wheat aleurone cells undergoing programmed cell death
(The American Society for Biochemistry and Molecular Biology, 2003)
The aleurone layer of cereal grains undergoes a gibberellin-regulated process of programmed cell death (PCD) following germination. We have applied a combination of ultrastructural and biochemical approaches to analyze ...

The yeast p24 complex is required for the formation of COPI retrograde transport vesicles from the Golgi apparatus
(Rockefeller University Press, 2008)
The p24 family members are transmembrane proteins assembled into heteromeric complexes that continuously cycle between the ER and the Golgi apparatus. These cargo proteins were assumed to play a structural role in COPI ...
