ABSTRACT:
The present invention relates to novel aminopeptidase derived fromBacillus licheniformis,a gene encoding the aminopeptidase, an expression vector containing the gene, a cell transformant transfected with the expression vector and a process for preparing a natural type protein using thereof. More particularly, the present invention relates to a gene encoding aminopeptidase which is cloned and manufactured using the recombinant DNA technique, an expression vector containing the gene, a cell transformant transfected with the expression vector and a recombinant aminopeptidase which is necessary to produce recombinant human growth hormone in a natural type protein and can be expressed in a high yield more stably and advantageously, compared with conventional methods for the purification.
