Discussion of SNAPG

Figure 1. Ligands interaction to SNAPG chain A. A) Ligands position in the structure are highlighted; B) Secondary structure of SNAPG chain A with ligands interaction indicated; and C) Various ligand interactions with SNAPG by covalent bonds (shown in red color), hydrogen bonding (cyan) and van der waals (green)

Figure 2. Various interaction of sulfanate ions

nanti aku mau jelasin ttg ligandnya

Tea: evolution linked with function.

SNAP-gamma protein evolutionary tree mostly contains more than 75% boostrapvalue. Thus, red dot signs was assign to represent more than 75% boostrap value. The value was indicated the degree of confidence about the branching order. As an example: in the diagram phylogenetic tree (see Figure 3, there is 39.0 boostrap value in branching Apis melifera and Tribolium castaneum. The boostrap value is below 75%, thus it could be concluded that the degree of confidence of branching tree in the correct order is far below 95%. On the other hand, boostrap value more than 75% or 75.00 means 95% confidence that the branching tree is in the correct order

As indicated in diagram above, SNAP-gamma protein was evolved in eukaryotes. There is no prokaryotes detected in the phylogenetic tree.

 Function (in various organism) = nunggu justine

Thus, it could be concluded that SNAP-gamma protein is important protein in eukaryotes animal.
