The thermostability and thermodinamics of formation of the enzyme-substrate complex of two oxidation products of chicken egg lysozyme with the tryptophane-62 residue modified to N'-formylkinurenine (with 2.5% activity) and kinurenine (with 27.5% activity) have been studied. In thermostability and pH effect on the substrate binding the lysozyme oxidation(More)
A functional completeness of summing amplifier with saturation in a multi-valued logic of an arbitrary value proven in previous works gives a theoretical background for analog implementation of fuzzy devices. Practical design techniques for multi-valued analog fuzzy controllers still have to be developed. Compared with the traditional approach, analog CMOS(More)
A lysozyme-like enzyme isolated from the culture broth of Staph. aureus 712 presented in its native state a lipoproteid complex. The lytic and antibacterial spectrum of the enzyme was similar to that of the egg albumin enzyme. However, the lipoproteid complex was somewhat superior to the egg albumin complex in its activity against Micrococcus lysodeikticus,(More)
The nature of the optical density of suspensions of Staph. aureus and M. luteus cells at various concentrations of chicken egg albumin lysozyme and two products of its chemical transformation was studied comparatively. The experiments were performed in 1/15 M Na-phosphate buffer at pH 6.2 and a temperature of 20-22 degrees C. It was shown that the decrease(More)
