WebCleaning compositions having engineered fatty acid alpha-dioxygenases and methods of using said compositions to provide a benefit by converting long chain fatty acids present in soils into 2-hydroperoxy fatty acids or terminal aldehydes. In the 1960s and early 1970s, scientists at University of Tübingen and at the Meiji Seika Kaisha Company independently discovered that species of Streptomyces bacteria produce a tripeptide they called bialaphos that inhibits bacteria; it consists of two alanine residues and a unique amino acid that is an analog of glutamate that they named "phosphinothricin". They determined that phosphinothricin irreversibly inhibits glutamine synthetase. Phosphinothricin was first synthesize…
