Fig. 5From: Engineering cofactor metabolism for improved protein and glucoamylase production in Aspergillus nigerThe pool sizes of amino acids for the A. niger reference strain B36 and three overexpression strains at steady state. Blocks in the heat map represent B36, OE gsdA (strain overexpressing gene gsdA), OE gndA (strain overexpressing gene gndA), and OE maeA (strain overexpressing gene maeA) from left to right. Amino acids labeled in yellow are the top five amino acids present in GlaA. Red arrows indicate the enzymes overexpressed. Quantified amino acid amounts and significance values are given in Additional file 1: Table S5Back to article page
