Nucleotide sequence, heterologous expression and novel purification of DNA ligase from Bacillus stearothermophilus(1).
The gene for DNA ligase (EC 6.5.1.2) from thermophilic bacterium Bacillus stearothermophilus NCA1503 has been cloned and the complete nucleotide sequence determined. The ligase gene encodes a protein 670 amino acids in length. The gene was overexpressed in Escherichia coli and the enzyme has been purified to homogeneity. Preliminary characterisation confirms that it is a thermostable, NAD(+)-dependent DNA ligase.
