Nucleotide and amino acid polymorphism in the gene for L-histidinol dehydrogenase of Escherichia coli K12
(Oxford University Press, 1990)
DNA sequence analysis of spontaneous histidine mutations in a polA1 strain of Escherichia coli K12 suggests a specific role of the GTGG sequence
(Springer-Verlag, 1990)
Spontaneously arising histidine mutations in an Escherichia coli K12 strain deficient for DNA polymerase I were analysed at the DNA sequence level. We screened approximately 150000 colonies and isolated 106 histidine ...
Cellular role of DNA polymerase I
(Journal of Basic Microbiology, 1990)
Escherichia coli possesses three well‐established DNA polymerases, I, II and III. DNA polymerase I (Pol 1) is the main repair polymerase in E. coli and also has a minor but important role in chromosomal replication. A major ...
Origin of rat β-globin haplotypes containing three and five genes
(Molecular Biology and Evolution, 1990)
We have reported in rat three adult β-gene haplotypes containing either five or three genes. Detailed sequence analysis reveals that the leftmost gene is the major gene and that at the opposite end downstream lies the minor ...
