Opis:
A lipase gene SR1 encoding an extracellular lipase was isolated from oil-contaminated soil and expressed in Escherichia coli. The gene contained a 1845-bp reading frame and encoded a 615-amino-acid lipase protein. The mature part of the lipase was expressed with an N-terminal histidine tag in E. coli BL21, purified and characterized biochemically. The results showed that the purified lipase combines the properties of Pseudomonas chlororaphis and other Serratia lipases characterized so far. Its optimum pH and temperature for hydrolysis activity was pH 5.5-8.0 and 37°C respectively. The enzyme showed high preference for short chain substrates (556.3±2.8 U/µg for C10 fatty acid oil) and surprisingly it also displayed high activity for long-chain fatty acid. The deduced lipase SR1 protein is probably from Serratia, and is organized as a prepro-protein and belongs to the GXSXG lipase family.

Opis:
Farnesyl diphosphate synthase (FPPS) is a key enzyme in isoprenoid biosynthesis which supplies sesquiterpene precursors for several classes of essential metabolites including sterols, dolichols, ubiquinones and carotenoids as well as substrates for farnesylation and geranylgeranylation of proteins. It catalyzes the sequential head-to-tail condensation of two molecules of isopentenyl diphosphate with dimethylallyl diphosphate. The enzyme is a homodimer of subunits, typically having two aspartate-rich motifs with two sets of substrate binding sites for an allylic diphosphate and isopentenyl diphosphate per homodimer. The synthase amino-acid residues at the 4th and 5th positions before the first aspartate rich motif mainly determine product specificity. Hypothetically, type I (eukaryotic) and type II (eubacterial) FPPSs evolved from archeal geranylgeranyl diphosphate synthase by substitutions in the chain length determination region. FPPS belongs to enzymes encoded by gene families. In plants this offers the possibility of differential regulation in response to environmental changes or to herbivore or pathogen attack.

Opis:
It is a well known, that the physical activity promotes mental health. Physically active people relatively rarely suffer from psychosomatic and depressive disorders. It is possible that the differences in gene activity in peripheral blood leukocytes may be associated with depression, especially genes participating in inflammatory response. Thus, the aim of our study was to investigate the levels of IL6 and IL10 mRNA and IL10/IL6 ratio in peripheral blood leukocytes in healthy, physically active individuals. One hundred healthy young men (20-23 years old) participated in this study. All of them declared regular physical activity. Participants were non-smokers, and consumed alcohol occasionally. To access genes expression, 2 ml of venous blood was collected. RNA isolation was performed and then the relative expression of IL6 and IL10 was calculated using quantitative real-time polymerase chain reaction (Q-RT-PCR). Pro and anti-inflammatory balance was calculated as 2^relative of IL10/ 2^relative expression of IL6. Low expression of tested genes was found in healthy young men. Mean expression for IL6 was 2^0.051 (n=90) and for IL10 2^0.08 (n=98). Mean ratio IL10/IL6 was 2^1.58. Higher expression of IL10 compared to IL6 may be essential not only for the physical performance but also for the mental health. Diverse reports in the literature may be associated with choosing various control groups, i.e. sedentary or older individuals. It is possible, that measuring the expression of IL6 and IL10 (especially the ratio IL10/IL6) in peripheral blood leukocytes may be useful in the assessment of depressive disorders. Thus, molecular study of active young men can confirm the need for physical activity among people suffering from depression, but further studies are needed, particularly among people with psychosomatic disorders.

Opis:
Genetic analysis of two rye interline crosses and a set of wheat/rye chromosomal addition lines was performed to reveal the mechanism underlying wide variation range of alpha-amylase activity in sound grain. The long arm of chromosome 6R was found to be responsible for increased enzyme synthesis during late stages of triticale grain maturation. Only nuclear genes seemed to control alpha-amylase activity, as reciprocal crosses between rye lines showed no maternal effects. Low enzyme activity showed complete dominance over high level of its synthesis. Segregation ratios, observed in F₂ and BC₁ crosses, indicated that recessive alleles at two independent duplicative loci underlie intensive alpha-amylase production.
