Responses of metabolic recycling systems to nitrogen stress in M. alpina. Heatmap shows changes in peptides (a) and metabolites (b) involved in nitrogen metabolism (especially amino acid metabolism) during fermentation. c Changes in enzymes involved in ubiquitin mediated proteolysis pathway. d Changes in key enzymes involved in cell autophagy.
