The non-essential UL50 gene of avian infectious laryngotracheitis virus encodes a functional dUTPase which is not a virulence factor.
The DNA sequence of the infectious laryngotracheitis virus (ILTV) UL50, UL51 and UL52 gene homologues was determined. Although the deduced UL50 protein lacks the first of five conserved domains of the corresponding proteins of mammalian alphaherpesviruses, the ILTV gene product was also shown to possess dUTPase activity. The generation of UL50-negative ILTV mutants was facilitated by recombinat...
متن کاملOrf virus ORFV121 encodes a novel inhibitor of NF-kappaB that contributes to virus virulence.
Orf virus (ORFV), the type member of the genus Parapoxvirus of the Poxviridae, has evolved novel strategies (proteins and/or mechanisms of action) to modulate host cell responses regulated by the nuclear factor-κB (NF-κB) signaling pathway. Here, we present data indicating that ORFV ORFV121, a gene unique to parapoxviruses, encodes a novel viral NF-κB inhibitor that binds to and inhibits the ph...
متن کاملThe ORF YBL042 of Saccharomyces cerevisiae encodes a uridine permease.
The purpose of this work was to identify the function of an open reading frame called YBL042, found during the systematic sequencing of Saccharomyces cerevisiae's chromosome II. The YBL042 gene product shows 70% similarity with the uracil permease and the allantoin permease encoded by FUR4 and DAL4, respectively. The mutation constructed by disruption of this ORF is allelic to the FUI1 gene pre...
متن کاملIdentification and characterization of pseudorabies virus dUTPase.
Sequence analysis within the long segment of the pseudorabies virus (PrV) genome identified an open reading frame of 804 bp whose deduced protein product of 268 amino acids exhibited homology to dUTPases of other herpesviruses. The gene was designated UL50 because of its colinearity with the homologous gene of herpes simplex virus type 1. An antiserum raised against a bacterially expressed frag...
متن کاملA meristem-related gene from tomato encodes a dUTPase: analysis of expression in vegetative and floral meristems.
A meristem-specific gene coding for deoxyuridine triphosphatase (EC 3.6.1.23) (dUTPase) in tomato was isolated, and its developmental expression in vegetative and floral apices was monitored. An 18-kD polypeptide, P18, was isolated as a consequence of its accumulation in arrested floral meristems of anantha mutant plants. The corresponding cDNA isolated from an expression library exhibited a 40...
