A 3.2-kb DNA fragment of the carbomycin biosynthetic region including the 3-O-acyltransferase gene (acyA) from Streptomyces thermotolerans was sequenced, and four ORFs were found in the fragment. The second ORF, designated ORF-A, was transcribed in the opposite direction to the other three ORFs. The first ORF was identified as carA, a gene for carbomycin resistance. The amino acid sequence of O...

orf is a mucocutaneous disease that occurs when non-intact skin comes into contact with contaminated sheep saliva. the lesions may complicate to lymphangitis or secondary bacterial infection, but systemic complications such as erythema multiforme, maculopapular rash, and generalized lymphadenopathy are rare. in this paper, we present two cases of erythema multiforme following orf disease.

We have previously demonstrated that two distinct transcripts are produced from ORF 50, the major transcriptional activating gene of herpesvirus saimiri. The products of these transcripts trans-activate the delayed-early ORF 6 promoter, though to different degrees. Deletion analysis demonstrated that the ORF 50 responsive elements are contained in a 132 bp fragment situated 127-259 bp from the ...

The complete genomic sequence of pothos latent virus (PoLV) has been determined. The genome organization is very similar to that of tombusviruses. The genome is 4415 nucleotides long and contains five ORFs. The 5' ORF (ORF 1) encodes a protein with a predicted molecular mass of 25 kDa and readthrough of its amber stop codon results in an 84 kDa protein (ORF 2). ORF 3 encodes the 40 kDa capsid p...

The herpesvirus saimiri open reading frame (ORF) 57 is homologous to genes identified in all classes of herpesviruses. It has previously been shown to regulate gene expression through a posttranscriptional mechanism. We demonstrate in this report that the expression of the ORF 57 protein leads to the cytoplasmic accumulation of glycoprotein B and capsid mRNAs. We also demonstrate that ORF 57 ha...

BACKGROUND Sixty (60) male West African Dwarf goats were reported with clinical signs of enlarged lymph nodes, scabs on the mouth, nose and ears. Two of the goats died and post mortem examination reveals enlarged submandibular lymph nodes and vesicular lesions on the tongue. Clinical diagnosis of Orf has been reported in Nigeria but this report is the confirmatory diagnosis of Orf in a suspecte...

Open reading frame (ORF) 50 protein is capable of activating the entire lytic cycle of Kaposi's sarcoma-associated herpesvirus (KSHV), but its mechanism of action is not well characterized. Here we demonstrate that ORF 50 protein activates two KSHV lytic cycle genes, PAN (polyadenylated nuclear RNA) and K12, by binding to closely related response elements located approximately 60 to 100 nucleot...
