The merozoite surface protein-1 represents a prime candi-date for development of a malaria vaccine. Merozoite sur-face protein-1 has been shown to demonstrate high-activity peptide binding to human red blood cells. One of the high-activity binding peptides, named 5501, located in the N-terminus (amino acid sequence MLNISQHQCVKKQ CPQNS) of the 19-kDa molecular mass fragment of mero-zoite surface protein-1, is conserved, nonimmunogenic and nonprotective.

We introduce the basic concepts and develop a theory for nonequilibrium steady-state biochemical systems applicable to analyzing large-scale complex isothermal reaction networks. In terms of the stoichiometric matrix, we dem-onstrate both Kirchhoff’s flux lawR‘J‘ ¼0 over a bio-chemical species, and potential law R‘l‘ ¼0overa reaction loop. They reflect mass and energy conservation, respectively.

Natural rubber fromHevea brasiliensisis a high molecular mass polymer of isoprene units withcis-configuration. The enzyme responsible for the cis-1,4-polymerization of iso-prene units has been identified as a particle-bound rubber transferase, but no gene encoding this enzyme has been cloned from rubber-producing plants. By using sequence information from the conserved regions of cis-prenyl chain elongating enzymes that were cloned recently, we have iso-lated and characterized cDNAs from H.

Although the annotation of the complete genome sequence ofMycoplasma pneumoniaedid not reveal a bacterial type I signal peptidase (SPase I) we showed experimentally that such an activity must exist in this bacterium, by determining the N-terminus of the N-terminal gene product P40 of MPN142, formerly called ORF6 gene. Combining mass spectrometry with a method for sulfonating specifically the free amino terminal group of proteins, the cleavage site for a typical signal peptide was located between amino acids 25 and 26 of the P40 precursor protein. ...

Retinoid receptors are ligand-dependent transcription factors belonging to the nuclear receptor superfamily. Retinoic acid (RARa, b, c) and retinoid X (RXRa, b, c) receptors mediate the retinoid/rexinoid signal to the transcriptional machineries by interacting at the first level with coactivators or corepressors, which leads to the recruitment of enzymatically active noncovalent com-plexes at target gene promoters.

We have isolated a laccase (lac1) from culture fluid ofVol-variella volvacea, grown in a defined medium containing 150lMCuSO4 , by ion-exchange and gel filtration chroma-tography. Lac1 has a molecular mass of 58 kDa as deter-mined by SDS/PAGE and an isoelectric point of 3.7. Degenerate primers based on the N-terminal sequence of purified lac1 and a conserved copper-binding domain were used to generate cDNA fragments encoding a portion of the lac1 protein and RACE was used to obtain full-length cDNA clones. ...
