Abbreviations for subsystems: A, amino acid biosynthesis and degradation; C, central or core metabolism; L, lipid and cell envelope biosynthesis; N, nucleotide biosynthesis and degradation; T, transport and energy-redox metabolism, (V) vitamin and cofactor biosynthesis. Pathways are classified according to the scheme presented in reference,63 wherein the primary metabolic pathways of functional significance are those of type I.
