Mutations that remove the 2’-OH of the A residue at the 30 end of the P-site tRNA result in a 106-fold reduction in catalysis rates. This “substrate-assisted catalysis”

2’-OH of the P-site tRNA may act as part of a “proton shuttle”

Counter-clockwise rotation starting at 0º gives negative dihedral angles from -1º through

90º ending at -180º (the same dihedral angle  as +180º).
