Schematic representation of the metabolic processes relevant to the mxaF fae transposon mutagenesis study. XoxF1 and XoxF2 oxidize methanol to formaldehyde, which accumulates to lethal levels in the fae mutant strain. If a process required for XoxF-dependent methanol oxidation is disrupted by a transposon insertion, formaldehyde is reduced or eliminated, and cells use succinate for growth. A dashed line around the formaldehyde transporter is to indicate that this function has not been demonstrated.
