Type A Pasteurella multocida, an animal pathogen, employs a hyaluronan [HA] capsule to avoid host defenses. PmHAS, the 972-residue membrane-associated hyaluronan synthase, catalyzes the transfer of both GlcNAc and GlcUA to form the HA polymer. To define the catalytic and membrane-associated domains, pmHAS mutants were analyzed. PmHAS1-703 is a soluble,(More)
The mouse Igkjrb protein specifically binds to the immunoglobulin Jk recombination signal sequence. The IGKJRB gene is highly conserved among many species such as human, Xenopus, and Drosophila. Using cDNA fragments of the mouse Igkjrb gene, we isolated its human counterpart, IGKJRB. The human genome contains one functional IGKJRB gene and two types of(More)
Sequence analysis of the 330-kilobase genome of the virus PBCV-1 that infects a chlorella-like green algae revealed an open reading frame, A98R, with similarity to several hyaluronan synthases. Hyaluronan is an essential polysaccharide found in higher animals as well as in a few pathogenic bacteria. Expression of the A98R gene product in Escherichia coli(More)
Type A Pasteurella multocida, a prevalent animal pathogen, employs a hyaluronan [HA] polysaccharide capsule to avoid host defenses. We utilized transposon insertional mutagenesis to identify the P. multocida HA synthase, the enzyme that polymerizes HA. A DNA fragment from a wild-type genomic library could direct HA production in vivo in Escherichia coli, a(More)
Selenoprotein S (SelS), a member of selenoprotein family, plays important regulatory function in inflammation and metabolic diseases. SelS expression is up-regulated response to the inflammatory stimulus in many mammal cells, animal models as well as patients. In order to further understand the function of SelS gene, molecular characterization and(More)
Fat mass and obesity-associated (FTO) gene codes for a nuclear protein of the AlkB related nonhaem iron and 2-oxoglutarate-dependent oxygenase superfamily, and is involved in animal fat deposition and human obesity. In this work, the molecular characterization and expression features of rabbit (Oryctolagus cuniculus) FTO cDNA were analysed. The rabbit FTO(More)
