We describe the cloning, nucleotide sequencing and expression in Escherichia coli of the major capsid component (VP60) from the Spanish field isolate AST/89 of rabbit haemorrhagic disease virus (RHDV). The sequence of the 3'-terminal 2483 nucleotides of the genome was found to be 95.4% identical to the German RHDV strain, showing ten changes in the deduced… (More)
We describe a program for protein sequence analysis which runs in IBM PC computers. Protein sequences are loaded from files in Mount-Conrad and Lipman-Pearson format. Seven features are analyzed: hydrophilicity, hydropathy, surface probability, side chain flexibility, antigenicity, secondary structure and N-glycosylation sites. Numeric results can be shown,… (More)
Subgenomic mRNA from a virulent isolate of porcine transmissible gastroenteritis virus (TGEV) was used to produce cDNA which was sequenced. Two non-overlapping open reading frames (ORFs) were identified. The largest, encoding a polypeptide of 382 amino acids (relative molecular mass (Mr) 43,483), was shown to be the viral nucleoprotein gene. The second ORF,… (More)
Subgenomic mRNA from a virulent isolate of porcine transmissible gastroenteritis virus (TGEV) was used to produce cDNA clones. Part of a new clone and a previously reported clone were sequenced and used to construct the viral gene for integral membrane protein. A single open reading frame (ORF) encoding a polypeptide of 262 amino acids, relative molecular… (More)
In a previous paper (Cármenes et al., 1984) we reported that UDP-glucose 4-epimerase from Saccharomyces was inactivated both in vivo and in vitro (crude extracts) by L-arabinose or D-xylose. In this paper, we report that pure epimerase requires the presence of UMP or UDP to be inactivated by sugars and that the inactivation is due to the reduction of the… (More)
L-Arabinose has been described as a gratuitous inducer of the yeast alpha-galactosidase. This has been found to be an artefact resulting from galactose contamination of commercial samples of L-arabinose. The inactivation produced on UDP-glucose 4-epimerase by the pentose does not amplify the inducer activity of contaminating D-galactose.
A software module for nonlinear regression analysis, based on the reliable Meyer-Roth algorithm (a modified damped least square algorithm), is presented. It allows both constrained and unconstrained optimization, and the use of a variety of weighting methods. Virtually any nonlinear function can be fitted, including those with several nondependent… (More)
