Despite the need for new antibiotics to treat drug-resistant bacteria, current clinical combinations are largely restricted to β-lactam antibiotics paired with β-lactamase inhibitors. We have adapted a Staphylococcus aureus antisense knockdown strategy to genetically identify the cell division Z ring components-FtsA, FtsZ, and FtsW-as β-lactam(More)
The unique S28 family of proteases is comprised of the carboxypeptidase PRCP and the aminopeptidase DPP7. The structural basis of the different substrate specificities of the two enzymes is not understood nor has the structure of the S28 fold been described. The experimentally phased 2.8 Å crystal structure is presented for human PRCP. PRCP contains an α/β(More)
HIV/AIDS continues to be a menace to public health. Several drugs currently on the market have successfully improved the ability to manage the viral burden in infected patients. However, new drugs are needed to combat the rapid emergence of mutated forms of the virus that are resistant to existing therapies. Currently, approved drugs target three of the(More)
Prostasin (also called channel activating protease-1 (CAP1)) is an extracellular serine protease implicated in the modulation of fluid and electrolyte regulation via proteolysis of the epithelial sodium channel. Several disease states, particularly hypertension, can be affected by modulation of epithelial sodium channel activity. Thus, understanding the(More)
The x-ray structure of the unactivated kinase domain of insulin-like growth factor-1 receptor (IGFRK-0P) is reported here at 2.7 A resolution. IGFRK-0P is composed of two lobes connected by a hinge region. The N-terminal lobe of the kinase is a twisted beta-sheet flanked by a single helix, and the C-terminal lobe comprises eight alpha-helices and four short(More)
We examined a sample of 112 adolescents convicted of homicide in adult court and sentenced to prison. To add to the descriptive literature regarding juvenile homicide, data are presented regarding their psychosocial characteristics, delineation of the crimes, and features of the victims. Family abuse in this sample was also explored in depth. Youngsters who(More)
The emergence of antibiotic-resistant strains of pathogenic bacteria is an increasing threat to global health that underscores an urgent need for an expanded antibacterial armamentarium. Gram-negative bacteria, such as Escherichia coli, have become increasingly important clinical pathogens with limited treatment options. This is due in part to their(More)
The cooperative assembly of FtsZ, the prokaryotic homologue of tubulin, plays an essential role in cell division. FtsZ is a potential drug target, as illustrated by the small-molecule cell-cycle inhibitor and antibacterial agent PC190723 that targets FtsZ. We demonstrate that PC190723 negatively modulates Staphylococcus aureus FtsZ polymerization(More)
The p90 ribosomal S6 kinases (RSKs) also known as MAPKAP-Ks are serine/threonine protein kinases that are activated by ERK or PDK1 and act as downstream effectors of mitogen-activated protein kinase (MAPK). RSK1, a member of the RSK family, contains two distinct kinase domains in a single polypeptide chain, the regulatory C-terminal kinase domain (CTKD) and(More)
