Проведены исследования воздействия химозина, смеси химозина-пепсина и пепсина на коагуляционные свойства молока, а также его УФ-концентрата. По результатам эксперимента наилучшая эффективность сычужного свертывания отмечена в пробах с пепсином, однако для более глубокого анализа кинетики гелеобразования целесообразно применение реологических методов. We conducted the research on the effect of chymozin, mixtures of chymosin-pepsin and pepsin on the coagulation properties of milk, as well as its UV concentrate. According to the results of our experiment, samples with pepsin show the best efficiency of rennet clotting. However, it is advisable to use rheological methods to conduct a more detailed analysis of the kinetics of gelation.

A set of growth arrest-specific (gas) genes whose expression is negatively regulated by serum has recently been identified. We report on the detailed analysis of one of these genes (gas3). The kinetics of regulation by the presence and absence of serum were investigated, and it was found that this gene is regulated at the post-transcriptional level. The encoded protein deduced from the nucleotide sequence showed some similarity to a mitochondrial oxyreductase, and in vitro translation established that the protein product is a transmembrane glycoprotein.

Recent developments in apparatus for the measurement of the rates of rapid reactions have made it possible to work with much smaller quantities of reactants than has previously been the case and have allowed the extension of work on the kinetics of mammalian haemoglobin to the haemoglobins of other species. In this paper the reactions of haemoglobin from the earthworm and lugworm with oxygen and carbon monoxide are described, and the results discussed in terms of the intermediate compound theory of Adair. The actual rates of reaction are of the same order as those for mammalian haemoglobin, but more detailed analysis shows appreciable species differences in the course of the reactions. These differences are probably attributable to variation in the arrangement of haem groups within the molecule.
