Sequence of the lacZ gene of Escherichia coli.

PMCID: PMC555066  PMID: 6313347

Abstract

The nucleotide sequence of the lacZ gene coding for beta-galactosidase (EC 3.2.1.23) in Escherichia coli has been determined. Beta-Galactosidase is predicted to consist of 1023 residues, resulting in a protein with a mol. wt. of 116 353 per subunit. The protein sequence originally determined by Fowler and Zabin was shown to be essentially correct and in an Appendix these authors comment on the discrepancies.
