YfcG and YghU form a Nu class of GSH transferases. The overall sequence similarity network contains 2,851 sequences and 97,144 edges. Edges represent BLAST e-values of 1e-18 or more stringent. Large nodes are colored by the classification of the amino acid sequence in SWISS-PROT and indicate a representative member of each subgroup as follows: Alpha, GSTA3_CHICK (UniProt Accession P26697); Beta, GSTB_ECOLI (P0ACA7); Mu, GSTM1_RAT (P04905); Nu, YFCG_ECOLI (P77526) and YGHU_ECOLI (Q46845); Omega, GSTO_HUMAN (P78417); Phi, GSTF1_MAIZE (P12653); Pi, GSTP_ONCVO (P46427); Sigma, GST_OMMSL (P46088); Tau, GSTU1_ORYSJ (Q10CE7); Theta, GSTT1_HUMAN (P30711); Zeta, GSTZ1_HUMAN (O43708).
