We have performed an screening on the extent of this response among different representative yeast species and the results show that this ability is displayed only by a few members of the Saccharomycetaceae family. However, all yeasts examined contain a gene related to that coding for regulatory trehalase in S. cerevisiae. This finding reveals that the operational distinction between regulatory and nonregulatory trehalase in yeasts is not a property of the enzyme by itself but relays on the expression of accompanying mechanisms able to modulate trehalase activity.</p>","PeriodicalId":77263,"journal":{"name":"Microbiologia (Madrid, Spain)","volume":"13 4","pages":"481-8"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20528489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is likely, therefore, that all viable organisms, from bacteria to mammals, are equipped with active extrusion machinery. When bacteria are attacked by antibiotics, they use these tactics to combat the drugs and to develop resistance. Drugs extrusion machinery in Gram-negative bacteria is complex, consisting of the inner membrane transporter which acts as an energy-dependent extrusion pump; a binding protein which presumably connect both membranes; and the outer membrane exit channel. The extrusion pump assemblies are often encoded by chromosomal genes and might be expressed by mutation(s) or induced in the presence of drug(s).</p>","PeriodicalId":77263,"journal":{"name":"Microbiologia (Madrid, Spain)","volume":"13 3","pages":"273-84"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20284791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
