The ultrasonic sound velocities of cross-linked orthorhombic hen egg-white lysozyme (HEWL) crystals, including a large amount of water in the crystal, were measured using an ultrasonic pulse-echo method. As a result, seven elastic constants of orthorhombic crystals were observed to be C-11 = 5.24 GPa, C-22 = 4.87 GPa, C-12 = 4.02 GPa, C-33 = 5.23 GPa, C-44 = 0.30 GPa, C-55 = 0.40 GPa, and C-66 = 0.43 GPa, respectively. However, C-13 and C-23 could not be observed because the suitable crystal planes could not be cut from bulk crystals. We conclude that the observed elastic constants of the cross-linked crystals are coincident with those of the intrinsic crystals without cross-linking. Moreover, the characteristics of the elastic constants in orthorhombic HEWL crystals are due to the fact that the shear elastic constants, C-44, C-55, and C-66, are softer than in tetragonal crystals. That is, the shear components, C-44, C-55, and C-66, are one half of those of the tetragonal crystals.
