  Abstract
We make a survey of resistance of 7510 proteins to mechanical stretching at constant speed as studied within a coarse-grained molecular dynamics model. We correlate the maximum force of resistance with the native structure, predict proteins which should be especially strong, and identify the nature of their force clamps.

Key Words: Go model, Protein Data Bank, atomic force microscope, mechanical clamp, molecular dynamics, stretching of proteins
