Fig. 3From: Structural and functional analysis of tomato sterol C22 desaturasePredicted tomato C22DES tertiary structure. a Overall predicted fold of tomato C22DES. b Predicted orientation of C22DES in a dioleoylphosphatidylcholine (DOPC) membrane. The predicted N-terminal transmembrane helix (TMH) and the membrane contact regions MCR1 and MCR2 are indicated. c and d Sequence logo of the consensus MCR1 and MCR2 sequences obtained from the alignment of the plant C22DES proteins indicated in Additional file 2: Table S1Back to article page
