A three-step chromatographic procedure was developed for purification of cardenolide 16'-O-glucohydrolase (CGH) from Digitalis lanata Ehrh. leaves, including Phenyl-Sepharose hydrophobic interaction chromatography followed by SP-Sepharose cation exchange and Q-Sepharose anion-exchange
Lanatoside 15'-O-acetylesterase (LAE) from in-vitro-cultivated cells of Digitalis lanata Ehrh. was isolated and partially sequenced. The enzyme was extracted with citrate buffer from acetone dry powder. It was purified in a two-step chromatographical procedure including Phenyl Sepharose hydrophobic
N-Terminal truncated forms of progesterone 5β-reductase (P5βR) were synthesized taking a full-length cDNA encoding for Digitalis lanata P5βR with a hexa-histidine tag attached at the C-terminus (rDlP5βRc) as the starting point. Four pETite-c-His/DlP5βR constructs coding for P5βR derivatives
