Metabolic Pathway Mapping
Growth rescue orders biosynthetic enzyme blocks. A mutant blocked later in a pathway can accumulate an intermediate that rescues a mutant blocked earlier. P grows when with R but not with Q; Q can grow with P, so P supplies a metabolite downstream of Q's block.
The cross-feeding pattern establishes the order y → x → z for the enzyme steps.
