Figure 2From: Genome-wide and molecular evolution analysis of the subtilase gene family in Vitis viniferaMultiple sequence alignment of the PA-subtilisin-like domain of grape subtilase group 1. The multiple alignment results clearly show the highly conserved PA-subtilisin-like domains among group 1 subtilase genes. The secondary structure elements of this domain are shown above the alignment. Cylindrical tubes represent α-helices and block arrows represent β-sheets.Back to article page
