PAPS-reductase of Escherichia coli. Correlating the N-terminal amino acid sequence with the DNA of gene cys H.
The DNA of the gene complementing a PAPS-reductase-deficient strain of Escherichia coli was sequenced. The N-terminal amino acid sequence of the purified PAPS-reductase confirmed that cys H is the structural gene for this enzyme. The open reading frame extends 732 bases and encodes for a peptide of Mr = 27927. The gene product is functionally active when supplemented with thioredoxin and immunologically related with the wild type enzyme.
