Abstract
Microbiological methods, compositions and transformants are used for production of organic products for controlling cellular properties. Extrachromosomal elements are used which are subject to external modulation for production of a control element. The change in the amount of production of the control element allows for enhanced expression of a gene producing a poly(amino acid) product. The change in production of the control element allowing for enhanced gene expression of the product is accompanied by amplification of the product producing gene.
