Summary of the impact of GSTM1/Gstm1-null genotype on GST activities

Isoform Specificity	Substrate	Human GSTM1-Null	Mouse Gstm1-Null	Substrate Classification
Total GSTs	CDNB	→	↓^{^a}	Mouse specific
Mu class GSTs	NBC	↓	↓	Common
Mu class GSTs	DCNB	→ (CLLOQ)	↓^{^a}	Mouse specific
Mu class GSTs	PBO	→ (BLLOQ)	↓	Mouse specific

→, no impact; ↓, decreased; CLLOQ, close to the lower limit of quantification; BLLOQ, below the lower limit of quantification.
