The signature motif of silkworm 42 UGT genes. Alignment of UGT amino acid sequences. Black and grey indicate identical and similar amino acids, respectively. Multiple sequence alignment was performed with CLUSTALW and amino-acid shading with BOXSHADE 3.21 http://www.ch.embnet.org/software/BOX_form.html. A consensus is indicated in the region of the UGT signature sequence. (FVA)-(LIVMF)-(TS)-(HQ)-(SGAC)-G- X(2) -(STG)-X(2)- (DE)-X(6)-P-(LIVMFA)-(LIVMFA)-X(2)-P-(LMVFIQ)-X(2)- (DE)-Q, (all amino acids that can concur at a given position are listed inside brackets; X indicted any amino acid; reviewed in [10])
