1. A method for the non-ribosomal production of a peptide of predefined amino acid sequence and length comprising the steps of:
- (a) providing a first DNA sequence containing the coding region of at least one amino acid activating domain of a peptide synthetase;
(b) providing a second DNA sequence containing the coding region of the carboxy-terminus of the last amino acid binding domain of a peptide synthetase downstream of the amino acid sequence of SEQ ID No. 1;
(c) fusing the 3'"'"'-end of the first DNA sequence to the 5'"'"'-end of the second DNA sequence to form a third DNA sequence;
(d) inserting the third DNA sequence into a vector selected from a group consisting of an expression or an integration vector to form a recombinant vector;
(e) transforming a microorganism with a recombinant vector of step (d);
(f) culturing the transformed microorganism to produce the novel peptide synthetase; and
(g) producing the peptide having a predefined sequence and length using the novel peptide synthetase.

- 12. A peptide synthetase comprising the first four amino acid activation domains of the surfactin synthetase, wherein the fourth amino acid activation domain is fused in the region downstream from the motif encoding the amino acid sequence SEQ ID No. 1 with the carboxy-terminus of the last amino acid binding domain of the surfactin synthetase, wherein the carboxy-terminus region contains at least 260 amino acid residues.
