PORTABLE, TEMPERATURE AND CHEMICALLY INDUCIBLE EXPRESSION VECTOR FOR HIGH CELL DENSITY EXPRESSION OF HETEROLOGOUS GENES IN ESCHERICHIA COLI

摘要

The present disclosure relates to nucleic acids comprising a sequence of SEQ ID NO: 1. The nucleic acid may be an isolated DNA and/or may be in the form of a plasmid or an expression vector. It may also be comprised in a microorganism. The nucleic acid may further comprise sequences that encode a protein. The self-replicating expression plasmid comprising a DNA sequence of the disclosure may be used to produce one or more protein. The production of one or more protein by a plasmid of the disclosure may be controlled by temperature and/or chemical induction. The disclosure also provides methods of obtaining high yields of proteins and methods for purifying such proteins, such as the LdK39 protein or a fragment thereof.
