Human cytomegalovirus immediate-early (IE) region 2 (0.732 to 0.740 map unit) begins 35 nucleotides downstream of IE region 1 (Stenberg et al., J. Virol. 49:190-199, 1984). A series of mRNAs that have different splicing patterns are transcribed from region 2. There is an unspliced 1,589-nucleotide exon present in minor amounts and two spliced exons (836 and(More)
The human cytomegalovirus open reading frames (ORFs) UL119 through UL115 (UL119-115) are located downstream of the immediate-early 1 and 2 transcription units. The promoter upstream of UL119 is active at all times after infection and drives the synthesis of a spliced 3.1-kb mRNA. The viral mRNA initiates in UL119, contains UL119-117 and UL116, and(More)
The human cytomegalovirus (HCMV) XbaI E cloned DNA fragment of approximately 20 kilobases can complement an adenovirus mutant (dl312) defective in the E1a viral gene product (D. J. Spector and M. J. Tevethia, Virology 151:329-338, 1986). This viral DNA fragment contains three immediate-early (IE) genes between 0.709 and 0.751 map units (M. F. Stinski, D. R.(More)
Adoptive immunotherapy with ex vivo-expanded antigen-specific cytotoxic T lymphocytes (CTLs) has been shown to clear viral infections and eliminate tumors in murine models. Clinical trials have also reported promising data for the use of adoptive immunotherapy to treat cytomegalovirus (CMV) and Epstein-Barr viral (EBV) infections in bone marrow transplant(More)
It is generally assumed that the machinery that transcribes genes is composed entirely of polypeptides. However, in vitro transcription by silkworm RNA polymerase III requires a transcription factor that is not a polypeptide. This component, TFIIIR, is distinct from the previously identified transcription components: RNA polymerase III, and the accessory(More)
Deacetylation of uridyldiphospho-3-O-(R-hydroxydecanoyl)-N-acetylglucosamine by LpxC is the first committed step in the Pseudomonas aeruginosa biosynthetic pathway to lipid A; homologous enzymes are found widely among Gram-negative bacteria. As an essential enzyme for which no inhibitors have yet been reported, the P. aeruginosa LpxC represents a highly(More)
As a strategy to increase the penetration of antibiotic drugs through the outer membrane of gram-negative pathogens, facilitated transport through siderophore receptors has been frequently exploited. Hydroxamic acids, catechols, or very close isosteres of catechols, which are mimics of naturally occurring siderophores, have been used successfully as(More)
LpxC [UDP-3-O-(R-3-hydroxymyristoyl)-GlcNAc deacetylase] is a metalloamidase that catalyzes the first committed step in the biosynthesis of the lipid A component of lipopolysaccharide. A previous study (H. R. Onishi, B. A. Pelak, L. S. Gerckens, L. L. Silver, F. M. Kahan, M. H. Chen, A. A. Patchett, S. M. Galloway, S. A. Hyland, M. S. Anderson, and C. R. H.(More)
