Question Answer
Sequence Identity A method of finding regions of similarity between proteins, and possibly how closely related they are
Sequence Identity Equation (No of identical residues/No of aligned residues) x 100
Root Mean- Square Deviation Used to estimate the difference between values predicted by a model and actual values
Calculating di between two residues Sqrt of [(x2-x1) + (y2-y1) + (z2-z1)]
RMSD Equation (Once Di is calculated for each aa) Sum of [(di)^2/no of residue pairs]^1/2
Value of significance for S.I 35%
RMSD Value = Identical Proteins 0
RMSD Value = Evolutionary Relationship 4>N
