[Abstract] Microbial production of alkanes employing synthetic biology tools has gained tremendous attention owing to the high energy density and similarity of alkanes to existing petroleum fuels. One of the most commonly studied pathways includes the production of alkanes by AAR (acyl-ACP (acyl carrier protein) reductase)-ADO (aldehyde deformylating oxygenase) pathway. Here, the intermediates of fatty acid synthesis pathway are used as substrate by the AAR enzyme to make fatty aldehyde, which is then deformylated by ADO to make linear chain alkane. However, the variation in substrate availability to the first enzyme of the pathway, i.e., AAR, via fatty acid synthesis pathway and low turnover of the ADO enzyme make calculation of yields and titers under in vivo conditions extremely ...
[摘要] [摘要] 由于烷烃的高能量密度和与现有石油燃料的相似性，使用合成生物学工具生产烷烃的微生物受到了广泛关注。最常研究的途径之一是通过AAR（酰基-ACP （酰基）载体蛋白）还原酶）-ADO（醛Deformylating 加氧酶）途径。在这里，中间体脂肪酸合成途径被用作基材由AAR Enzym E要使脂肪醛，然后是Deformylated 通过ADO，使线性链烷烃。但是，即该途径的第一种酶的底物利用率的变化，即，AAR，通过脂肪酸合成途径和ADO酶的低周转率，使得在体内条件下的产量和效价的计算极为困难。在体内测定中，将确定的ADO酶底物外加到培养基中有助于监测菌体的流入。因此，该底物提供了更准确的产物收率测量方法。在此方案中，我们包括用于实施体内测定法以监测大肠杆菌中烷烃生产的详细指南。
[背景] 利用工程微生物生产烷烃的研究已广受欢迎，因为它提供了一种有吸引力的替代方案，可减少对化石燃料的依赖，同时减轻气候变化的影响（Lee 等，2008；Knothe ，2010； Lu，2010； Schirmer 等。人，2010;谭等人。，2011）各种途径已被发现或人工Assemb ...
