For instance, the precision values for and for the AdjN data can be read from the -axis in Figure 1 at ... precision values above 50% for the first 10% of the list, but is outper- formed by the t-test afterwards. Looking at the first 40% of the data, there is a big gap betwe...

... [9,19,24,25]. The main goal of the present study was to investi- gate further the resemblance between hcHAT proteins and the enzymes from the a-amylase family. We there- fore carried out a bioinformatics ... knowl- edge, from Urochordata (Fig. 1). The second sequence feature clearly visible from the alignment is whether the individual catalytic residues, or even the en...

... genomic DNA. For that rea- son, we amplified the open reading frame from cDNA. For the second of the two potential glycerol dehydro- genases, we predicted no introns and therefore ampli- fied the open ... protein was purified and then used for further analysis. In the reductive reaction, the Michaelis–Menten con- stant K m for DHA was 1 mm, and the K m for NADPH was 50...

The theoric molecular mass, 23.6 kDa, calculated from the database sequence after removal of the N-terminus signal peptide, is in agreement with the value of 25–26 kDa estimated from the ... activation of the iron trans- port systems [37]. Therefore, they are crucial in controlling iron storage and homeostasis in the plant cells. Other functions of plant ferritins a...
