We recently identified the phaG(Pp) gene encoding (R)-3-hydroxydecanoyl-ACP:CoA transacylase in Pseudomonas putida, which directly links the fatty acid de novo biosynthesis and polyhydroxyalkanoate (PHA) biosynthesis. An open reading frame (ORF) of which the deduced amino acid sequence shared about 57% identity with PhaG from P. putida was identified in the P. aeruginosa genome sequence. Its co...

SpoU is encoded by the fourth open reading frame (ORF) of the spo operon of Escherichia coli (1). The 5'-terminal gene of this operon, gmk, encodes guanylate kinase; the second gene, rpoZ, encodes the w subunit of RNA polymerase; the third gene, spoT, encodes ppGpp hydrolase, and the 3'-terminal gene, recG, encodes a helicase-like protein involved in recombination (1 and references therein). Sp...

We have cloned and sequenced a 1.5-kb chromosomal fragment of Thermus thermophilus which promoted the overproduction of carotenoids in T. thermophilus. An open reading frame (ORF-A) coding for a polypeptide with 289 amino acids was responsible for carotenoid overproduction. The putative ORF-A protein showed significant homology with the amino acid sequences of crtB gene products (phytoene synth...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of three malignancies associated with AIDS and immunosuppression. Tumor cells harbor latent virus and express kaposin (open reading frame [ORF] K12), v-FLIP (ORF 71), v-Cyclin (ORF 72), and latency-associated nuclear antigen (LANA; ORF 73). ORFs 71 to 73 are transcribed as multicistronic RNAs initiating from adjacent constitu...

Complementary DNA clones representing approximately 6100 nucleotides of potato leafroll virus (PLRV) were generated, restriction-mapped, and partially sequenced. Within one of the cDNA clones an open reading frame (ORF) encoding a 23K protein was identified and further characterized. Amino acid sequence comparison of this protein showed significant homology (47.1%) with the barley yellow dwarf ...

in this study, the full-length m2 gene of the avian influenza virus (h9n2) was isolated, analyzed and studied in detail. total rna was extracted and cdna of the m2 mrna was obtained by reverse transcriptase polymerase chain reaction (rt-pcr) using random hexamer oligoes; specific primers were used for amplification of the m2 open reading frame (orf) region. pcr was able to amplify the desirable...

We have analyzed synonymous codon usage in the genome of A. tamarense CCMP 1598 for protein-coding sequences from 10865 expressed sequence tags (ESTs). We reconstructed a total of 4284 unigenes, including 74 ribosomal protein and 40 plastid-related genes, from ESTs using FrameDP, an open reading frame (ORF) prediction program. Correspondence analysis of A. tamarense genes based on codon usage s...

Here, we characterized the structure and function of the coagulation factor II (FII) gene in grass carp and determined its role in coagulation mechanisms. The FII gene EST was obtained using a constructed splenic transcriptome database; the full-length FII gene sequence was obtained by 3' and 5' RACE. The open reading frame (ORF) of FII was cloned and the full-length gene was found to be 1718 b...

Transient expression assays have shown that the varicella-zoster virus (VZV) open-reading frame (ORF) 29 gene product can act as a modulator of VZV gene expression. The ORF 29 protein alone does not appear to have any effect on transcription; however, in its presence, changes in the level of reporter gene activity mediated by the VZV immediate early (IE) 62 major transactivator are seen. Increa...

Endornaviruses have large double-stranded RNA (dsRNA) genomes that carry a single open reading frame (ORF). Here we report the complete genome of a novel endornavirus, assembled from next-generation sequence data generated from Vitis vinifera-extracted dsRNA. Two different fungal hosts have been identified for this virus, suggesting that horizontal transmission of the virus is possible.
