Efficient methods and universal DNA elements are eagerly required for the expression of proteins and the production of target chemicals in synthetic biology and metabolic engineering. This paper develops a customized-design approach by utilizing the host-independent T7 expression system (HITES), which facilitates the rational design and rapid construction of T7 expression systems. Firstly, the EL (Upper-limit value of initial enzyme activity) value is discovered to play a pivotal factor in the successful construction of the T7 expression system, different host strains exhibit varying EL values, and this study presents a method to measure the EL values.

The potential of using fecal microbiota signatures to aid autism spectrum disorder (ASD) detection is still not fully explored. Here, we assessed the potential of different levels of microbial markers (taxonomy and genome) in distinguishing children with ASD from age and gender-matched typically developing peers ( = 598, ASD vs TD = 273 vs 325).
