Popis: | Indolyl-3-alkane alpha-hydroxylase was isolated from soil isolate organism, Pseudomonas XA, by affinity chromatography on indolyl-agarose, using different indole derivatives (L-tryptophan, N-acetyl-L-tryptophan, indole-3-carboxaldehyde and 3-indole-acrylic acid). With the exception of N-acetyl-L-tryptophan-agarose, excellent yields were obtained. The affinity chromatography step caused a 15-fold increase in the specific activity of the enzyme. The purity of indolyl-3-alkane alpha-hydroxylase was comparable to the preparations obtained by conventional isolation techniques; however, it showed a 7- to 10-times higher overall yield. Affinity purified indolyl-3-alkane alpha-hydroxylase exhibited essentially one band in polyacrylamide gel electrophoresis and on isoelectric focusing. |
