Expression profiles of heterologous genes driven by PLRA3 and PLRA4 in P. pastoris.
(A) Schematic representation of plasmid pGHLRA3α for heterogeneous gene expression in P. pastoris. (B) β-galactosidase activity under the control of PLRA3, PLRA4 and PGAP at various time points. (C) Production of recombinant β-galactosidase using PLRA3, PLRA4 and PGAP for various durations. (D) Green fluorescence under the control of PLRA3, PLRA4 and PGAP; ‘C’ represents P. pastoris GS115, which was used as a control.
