'Burkholderia pseudomallei, the causative agent of melioidosis, is inherently resistant to a variety of antibiotics including aminoglycosides, macrolides, polymyxins, and beta-lactam antibiotics. Despite resistance to many beta-lactams, ceftazidime and beta-lactamase inhibitor-beta-lactam combinations are commonly used for treatment of melioidosis. Here, we examine the enzyme kinetics of beta-lactamase isolated from mutants ... More
Characterization of the interaction between P143 and LEF-3 from two different baculovirus species: Choristoneura fumiferana nucleopolyhedrovirus LEF-3 can complement Autographa californica nucleopolyhedrovirus LEF-3 in supporting DNA replication.

The baculovirus protein P143 is essential for viral DNA replication in vivo, likely as a DNA helicase. We have demonstrated that another viral protein, LEF-3, first described as a single-stranded DNA binding protein, is required for transporting P143 into the nuclei of insect cells. Both of these proteins, along with ... More
Recognition of nonhybridizing base pairs during nucleotide excision repair of DNA.

Nondistorting C4' backbone adducts serve as molecular tools to analyze the strategy by which a limited number of human nucleotide excision repair (NER) factors recognize an infinite variety of DNA lesions. We have constructed composite DNA substrates containing a noncomplementary site adjacent to a nondistorting C4' adduct to show that ... More
