Amino acid sequences of regulator to express catechol catabolic enzymes and gene sequences thereof

摘要

PURPOSE: An amino acid sequence of a regulator protein regulating the expression of catechol catabolic enzymes and a nucleotide sequence thereof are provided, thereby effectively expressing the catechol catabolic enzymes. CONSTITUTION: A transcription regulating protein of catechol catabolic enzyme is isolated from Streptomyces setonii (ATCC 39116) and has the amino acid sequence of SEQ ID NO: 2, wherein catechol catabolic enzyme decomposes catechol to 3-oxoadipate enol lactone. A gene encoding the transcription regulating protein of SEQ ID NO: 2 has the nucleotide sequence of SEQ ID NO: 1.
