520 3 |a Microgravity and simulated microgravity (SMG) have quite significant effects on numerous microbial cellular processes. The effects of SMG on the production of recombinant proteins and transcription profiling in prokaryotic and eukaryotic expression host have been investigated. The present study showed that SMG significantly enhanced the specific productivities and activities of the reporter enzymes PGUS and AtXYN that were expressed in recombinant Pichia pastoris. Proteomic profiling revealed that 21 proteins were significantly up-regulated and 35 proteins were drastically down-regulated at the stationary phase, when the recombinant P. pastoris responded to SMG. Six strongly up-regulated genes, TPX, FBA, PGAM, ENO, SBA1, and AKR-E, involved in the oxidative stress response, methanol metabolism, glycolytic pathway, and protein folding, were selected to analyze their impacts on recombinant protein production by co-overexpression in the shaker flask fermentation. The co-overexpressed strains, particularly TPX, FBA, and PGAM, demonstrated promising results with approximately 2.46-fold, 1.58-fold, and 1.33-fold increases in the specific yields of PGUS compared to the control after 48h of methanol induction, respectively. In the meantime, the corresponding PGUS specific activities were increased by 2.33-fold, 2.09-fold, and 1.32-fold, respectively. Thiol peroxidase (TPX), which is involved in the oxidative stress response, significantly influenced the transcriptional levels of the reporter gene PGUS. The present study provides valuable information for further exploration of the molecular mechanism of P. pastoris response to SMG and facilitates simulated microgravity for finding novel helper factors to rationally engineer the strains in normal fermentation by using proteomic studies.
