MeSH note : consists of 3 multifunctional enzymes involved in the biosynthesis of the cyclic decapeptide
tyrocidine; tyrocidine synthetase 1 activates the phenylalanine & racemizes it; tyrocidine
sythetase 2 activates proline, phenylalanine & phenylalanine in positions 2,3 & 4
& racemizes phenylalanine at position 4; tyrocidine synthetase 3 catalyzes the activation
of the remaining 6 amino acids; see also record for tyrocidine synthetase 1; GenBank
AF004835 (tycB and tycC);
