Effect of Nitrogen Source and Inorganic Phosphate Concentration on Methanol Utilization and PEX Genes Expression in Pichia pastoris

Figure 6

Proposed model of AOX1 gene regulation by nitrogen source. Activity of AOX1 promoter is modified depending on nitrogen source via Tor-signaling pathway. Proximate signal transduction is provided by proteins, involved in regulation of AOX1 gene by carbon source.
