Using genome mining of natural @( 73 ) Assignee : Centro de Investigación y de Estudios products , we predicted that SL10883 - 5 genes encode an Avanzados del Instituto Politécnico unprecedented biosynthetic system , unusually small ( 4 . 6 Nacional , Ciudad de México , CDMX Kbp ) , which produces an acylated peptide aldehyde . (MX ) Because of the chemical characteristics of the predicted compound , we postulated its anti - proteolytic activity , which (21 ) Appl . No .: 15 /537 , 125 we confirmed by identifying and purifying this compound through metabolic profiles of HPLC and MS of the mutated ( 22 ) PCT Filed : Dec . 14 , 2015 strain lacking these three genes and the wild strain . To this ( 86 ) PCT No. : PCT/ IB2015 /059566 objective , we identified the conditions wherein these genes are strongly expressed . The livipeptin was purified and its $ 371 ( c ) ( 1 ) , inhibitory activity on the proteolytic activity of selected (2 ) Date : Jun . 16 , 2017 proteases was demonstrated in vitro . The design of an expression cassette for its heterologous expression is also ( 30 ) Foreign Application Priority Data described plus its use for heterologous protein production .
