Figure 3From: Systematic screening of glycosylation- and trafficking-associated gene knockouts in Saccharomyces cerevisiaeidentifies mutants with improved heterologous exocellulase activity and host secretionExtracellular PCX activity in 50 ml supernatants of different hosts as measured by 4-MUC assay. (A) Total extracellular activity; (B) specific extracellular activity; and (C) total extracellular proteins. WT: BY4741; ∆M: mnn10 null mutant;∆V: vps21 null mutant; ∆P: pmt5 null mutant; ∆M∆P: mnn10∆pmt5∆ double knockout strain; ∆P∆V: pmt5∆vps21∆ double knockout strain; CBHI: exocellulase of Trichoderma ressei.Back to article page
