Helen Kruger Service Excellence Award for outstanding committee work, clinical service and continuing education. Petra Volmer, professor of veterinary biosciences and the Veterinary Diagnostic Laboratory, and director of the Veterinary Clinical Toxicology Residency Program, received the Dr. Lois Hoyer, professor of veterinary pathobiology, won the Dr. Helen Kruger Teaching Excellence Award for teaching with enthusiasm, dedication, clarity and creativity and integrating subject concepts into the overall framework of the veterinary curriculum. Tom Graves, professor of veterinary clinical medicine, won the Dr. Eight people received a $1,000 cash prize and a framed certificate for the college-sponsored excellence awards in various categories. Anderson, associate director of the Beckman Institute for Advanced Science and Technology, was nominated by Cathy Rix, assistant program administrator at the Beckman Institute.įaculty and staff members, and graduate students of the College of Veterinary Medicine were honored for service excellence or length of service on Sept. The Secretariat named Van Anderson the 2006 Boss of the Year. He receive the award at the institute’s meeting this month in San Francisco and will speak before the members at the Process Development Division dinner. Braatz is being recognized for his contributions in pharmaceutical crystallization. The award is sponsored by Pfizer and recognizes significant technical contributions to the advancement of process development within research, teaching or regulatory activities. Richard Braatz, professor of bioengineering, will receive the 2006 Excellence in Process Development Research Award from the Process Development Division of the American Institute of Chemical Engineers. This honor recognizes a member of academia who significantly contributes to and promotes Hispanic education in the engineering, science and math disciplines.

These repeats code for a previously undescribed structure designated the poly(Ψ) motif. DNA sequencing and PCR analysis of neuO from strains that had undergone random capsule form variation showed that slip strand DNA mispairing or unequal recombination resulted in gain or loss of (5′-AAGACTC-3′) n heptanucleotide repeats (where n ≈ 14–39) located in the neuO 5′ region. Analysis of mutants that accumulate intracellular polysialic acid because of export defects ( kpsM and kpsS) or an inability to synthesize the sialic acid precursor, N-acetylmannosamine ( neuC), indicated that NeuO does not require constant association with its substrate for activity. Deleting neuO eliminated enzymatic activity, which was restored by complementation in trans, and confirmed by 13C-NMR analysis of the acetylated product. Molecular epidemiological analysis established concordance between O-acetyltransferase and CUS-3 in a set of E. coli K1 O-acetyltransferase encoded by neuO is genetically linked to the endo-neuraminidase tail protein gene of a chromosomal accretion element, designated CUS-3, with homology to lambdoid bacteriophage.
Despite the biological importance of O-acetylation, no sialic or polysialic acid O-acetyltransferase has been identified in any system. Potential O-acetylation of the sialic acid residues of Escherichia coli K1, groups W-135, Y, and C meningococci, and group B Streptococcus capsular polysaccharides modifies their immunogenicity and susceptibility to glycosidases.
