Abstract | The present invention relates to a recombinant expression vector which is prepared by inserting a human parathyroid hormone gene containing a urokinase-specific cleavage site into an L-arabinose inducible vector containing a phosphoribulokinase gene fragment of Rhodabacter sphaeroides or its mutated gene as a fusion partner, or its mutate gene as a fusion partner, a recombinant microorganism transformed with the said expression vector, and a process for preparing human parathyroid hormone on a large scale by cultivating the said microorganism in a medium containing L-arabinose. In accordance with the invention, a recombinant human PTH having the same activity of the native human PTH can be prepared in a high yield through the precise control of induction by a manufacturing process which comprises a step of inducing expression of fusion protein in the microorganism transformed with the recombinant expression vector by L-arabinose. |
