摘要: This invention provides a series of low-copy number plasmids comprising restriction endonuclease recognition sites useful for cloning at least three different genes or operons, each flanked by a terminator sequence, the plasmids containing variants of glucose isomerase promoters for varying levels of protein expression. The materials and methods are useful for genetic engineering in microorganisms, especially where multiple genetic insertions are sought.

摘要: The present invention provides an improved method for the production of 1,3-propanediol from a variety of carbon sources in an organism capable of 1,3-propanediol production and comprising DNA encoding protein X of a microorganismal dehydratase or protein X in combination with at least one of protein 1, protein 2 and protein 3, which proteins are comparable to those encoded by orfY, orfX and orfW, respectively from a microorganismal dha regulon. The protein X may be isolated from a diol dehydratase or a glycerol dehydratase. The present invention also provides host cells comprising protein X that are capable of increased production of 1,3-propanediol.
