In vitro activity of the hairpin ribozyme derived from the negative strand of arabis mosaic virus satellite RNA.
The negative strand of the satellite RNA of tobacco ringspot virus [(-)sTRSV] is a self-cleaving RNA, of which self-cleaving domain is called the hairpin ribozyme. The negative strand of the satellite RNA of arabis mosaic virus [(-)sArMV] has been suggested to have a hairpin ribozyme-like secondary structure, and we have previously shown that this hairpin domain of (-)sArMV has ribozyme activit...
متن کاملSubcellular localization and expression of bamboo mosaic virus satellite RNA-encoded protein
The satellite RNA of bamboo mosaic virus (satBaMV) has a single open reading frame encoding a non-structural protein, P20, which facilitates long-distance movement of satBaMV in BaMV and satBaMV co-infected plants. Immunohistochemistry and immunoelectron microscopy revealed that the P20 protein accumulated in the cytoplasm and nuclei in co-infected cells. P20 and the helper virus coat protein (...
متن کاملThe nucleotide sequence of a satellite RNA associated with arabis mosaic nepovirus.
The nucleotide sequence of a satellite RNA (satRNA) associated with a lilac isolate of arabis mosaic virus (ArMV) was determined from cDNA copies. The sequence was 1104 nucleotides in length excluding the poly(A) tail, contained a long open reading frame which encodes a polypeptide of 360 amino acids, with an Mr of 39K. Nucleotide sequence comparisons revealed that the ArMV-associated satRNA sh...
متن کاملTransgenic plants and insect cells expressing the coat protein of arabis mosaic virus produce empty virus-like particles.
The 3' end of the RNA-2 of arabis mosaic virus (ArMV) was cloned and sequenced. The N-terminal amino acid sequence of the virion coat protein was determined by Edman degradation and the corresponding coding region identified. This gene was modified at the 5' and 3' ends by use of mismatched primers in the polymerase chain reaction (PCR), in order to facilitate the cloning of the gene, and to pr...
متن کاملBamboo mosaic potexvirus satellite RNA (satBaMV RNA)-encoded P20 protein preferentially binds to satBaMV RNA.
A satellite RNA of 836 nucleotides [excluding the poly(A) tail] depends on the bamboo mosaic potexvirus (BaMV) for its replication and encapsidation. The BaMV satellite RNA (satBaMV) contains a single open reading frame encoding a 20-kDa nonstructural protein (P20). The P20 protein with eight histidine residues at the C terminus was overexpressed in Escherichia coli. Experiments of gel retardat...
