英文摘要Zn2+ is largely discharged from many industries and poses a severe threat to the environment, making its remediation crucial. Encapsulins, proteinaceous nano-compartments, may protect cells against environmental stresses by sequestering toxic substances. To determine whether hemerythrin-containing encapsulins (cEnc) from anammox bacteria Ca. Brocadia fulgida can help cells deal with toxic substances such as Zn2+, we transferred cEnc into E.coli by molecular biology technologies for massive expression and then cultured them in media with increasing Zn2+ levels. The engineered bacteria (with cEnc) grew better and entered the apoptosis phase later, while wild bacteria showed poor survival. Furthermore, tandem mass tag-based quantitative proteomic analysis was used to reveal the underlying regulatory mechanism by which the genetically-engineered bacteria (with cEnc) adapted to Zn2+ stress. When Zn2+ was sequestered in cEnc as a transition, the engineered bacteria pre-sented a complex network of regulatory systems against Zn2+-induced cytotoxicity, including functions related to ribosomes, sulfur metabolism, flagellar assembly, DNA repair, protein synthesis, and Zn2+ efflux. Our findings offer an effective and promising stress control strategy to enhance the Zn2+ tolerance of bacteria for Zn2+ remediation and provide a new application for encapsulins.
