Resolution of Holliday junctions in vitro requires the Escherichia coli ruvC gene product. (1991)
Journal Article
Connolly, B., Parsons, C., Benson, F., Dunderdale, H., Sharples, G., Lloyd, R., & West, S. (1991). Resolution of Holliday junctions in vitro requires the Escherichia coli ruvC gene product. Proceedings of the National Academy of Sciences, 88(14), 6063-6067

In previous studies, Holliday junctions generated during RecA-mediated strand-exchange reactions were resolved by fractionated Escherichia coli extracts. We now report the specific binding and cleavage of synthetic Holliday junctions (50 base pairs l...

Location of a mutation in the aspartyl-tRNA synthetase gene of Escherichia coli K12. (1991)
Journal Article
Sharples, G., & Lloyd, R. (1991). Location of a mutation in the aspartyl-tRNA synthetase gene of Escherichia coli K12. Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 264(3), 93-96

A mutation (tls-1) that confers a temperature-sensitive growth phenotype in Escherichia coli was shown by DNA cloning and sequencing to be an allele of aspS, the gene for aspartyl-tRNA synthetase. The mutation, which lies near minute 41 on the geneti... Read More about Location of a mutation in the aspartyl-tRNA synthetase gene of Escherichia coli K12..
