Popis: Synthetic DNA fragments encoding the entire open-reading frame of human heparin-binding growth factor-1 (HBGF-1 beta) and its NH2-terminal truncated form (HBGF-1 alpha) were constructed. When both constructs were expressed in Escherichia coli under control of the trp-lac promoter, biologically active HBGF-1 alpha, but not HBGF-1 beta was produced in high yield. However, high level expression of HBGF-1 beta was obtained using the T7 polymerase expression vector. Computer analysis of HBGF-1 beta predicts the potential for the formation of exaggerated RNA secondary structure near the translation initiation codon and this could be implicated in contributing to the poor translation of HBGF-1 beta under the trp-lac promoter.
