Genome-wide characterization of i-motifs and their potential roles in the stability and evolution of transposable elements in rice

by

I-motifs (iMs) are non-canonical DNA secondary structures that fold from cytosine (C)-rich genomic DNA regions termed putative i-motif forming sequences (PiMFSs). The structure of iMs is stabilized by hemiprotonated C-C base pairs, and their functions are now suspected in key cellular processes in human cells such as genome stability and regulation of gene transcription. In … Read more

Recombinant Bovine Enterokinase (rb-EK)

by

Enterokinase (EC 3.4.21.9) is a serine proteolytic enzyme, which can recognize the sequence of ASP ASP Lys (DDK) in the protein efficiently and specifically, hydrolyze the peptide bond at the C-terminal of lysine (Lys, K), produce cleavage, hydrolyze trypsinogen to trypsin in the organism. Because enterokinase has high specificity and efficient enzymatic cleavage, it is … Read more

Nitrogen assimilation and photosynthetic capacity of wheat genotypes under optimal and deficient nitrogen supply

The performance of two varieties of contrasting Bulgarian wheat (Slomer, a former cultivar and enola, a modern half-dwarf) with nitrogen deficiency has been compared by measuring biochemical parameters characterizing absorption and assimilation as well as growth and the photosynthetic activity of young young plants. The old genotype has made better photosynthetic capacity, higher assimilation, expressed … Read more
