It was previously shown that the phosphoprotein (P) of vesicular stomatitis virus must undergo phosphorylation-dependent multimerization to become transcriptionally active. Phosphorylation at S-60 and/or T-62 by casein kinase II or substitution of these residues by D is required for multimer formation. We now find that substitution of either one of these(More)
Casein kinase-II (CK-II) is a widely distributed protein kinase, which plays numerous roles in the regulation of transcription through modification of transacting transcription factors. Phosphorylation of vesicular stomatitis virus (VSV) P protein by CK-II was found to be both necessary and sufficient for transcriptional activation. Upon treatment of P by(More)
AxCesD protein required for bacterial cellulose biosynthesis in Acetobacter xylinum was overexpressed in E. coli, purified and crystallized. Single crystals of SeMet-substituted AxCesD were obtained by the sitting-drop vapor-diffusion method. The crystal belongs to the primitive trigonal space group P3 2, with unit-cell parameters a = b = 77.7 A, and c =(More)
The phosphoprotein (P) of vesicular stomatitis virus was previously shown to assemble into a homomultimer upon phosphorylation by casein kinase II. It thus acquired transcriptional activity, including the ability to bind to the other two transcriptional components, the polymerase L and the N-RNA template. This multimer has now been found to be a trimer(More)
The protein kinase inhibitor staurosporine has been found to inhibit vesicular stomatitis virus transcription in infected BHK cells. Both primary and secondary transcription were virtually abolished by 10 microM staurosporine. In contrast, transcription by purified virions, or by nucleocapsids isolated from them, was unaffected by staurosporine.(More)
The biosynthetic pathway of the off-flavour terpenoid alcohol 2-methylisoborneol (2-MIB) requires geranyl pyrophosphate methyltransferase (GPPMT) to methylate GPP before the cyclization reaction. GPPMT is the first example of an S-adenosyl-L-methionine-dependent methyltransferase that acts on general intermediates such as geranyl pyrophosphate and farnesyl(More)
