Interaction of 4-carboxy-2-hydroxymuconate-6-semialdehyde dehydrogenase with Reactive Blue 2 and related dyes.

abstract：:Pure recA protein was easily obtained from Escherichia coli harboring plasmid pTM-2 which carried the recA gene by two chromatographic steps on phosphocellulose and DEAE-cellulose. RecA protein was stable in the pH range of 6 to 9 at 25 degrees C. RecA protein was found to aggregate highly under these conditions. Lowe...
