Introduction

Li et al. [1] analyzed the proteomic characteristics of Halomonas TD01 using SDS-PAGE. They identified a strongly expressed endogenous gene encoding a porin and preliminarily determined its promoter region. Furthermore, they identified the core region and constructed a constitutive promoter library by randomizing the sequences between the -35 and -10 regions. Shen et al. [2] performed 3-nucleotide saturation mutagenesis upstream of the -10 box and 4-nucleotide saturation mutagenesis within the -10 box to further expand the promoter library. We have only included the porin constitutive promoters that are relevant to our team.
