We have performed for the first time micro-Raman studies of lysozyme crystals for the temperatures lower than the room one (in the range 282-300K). Anomalous temperature dependence of the positions of Raman scattering bands has been detected and discussed, which corresponds to the crystalline lysozyme structure in the vicinity of T=285K.
