| Abstract: | Two acyl-CoA-binding-protein (ACBP) isoforms were isolated from proembryogenic masses of Digitalis lanata Ehrh. by column chromatography and preparative HPLC. The ACBPs had molecular masses of 9926 and 9997 Da, respectively. Partial sequence data indicated high similarity to each other and to ACBPs of other plant species such as Ricinus communis, Brassica napus and Arabidopsis thaliana. The isolated ACBPs bound palmitoyl-CoA with high affinity as determined by isoelectric-point shift. Received: 29 May 1999 / Accepted: 28 August 1999 |
