... hexokinases have lost intron 2, which is present in the other moss hexokinases, includ- ing the type D hexokinases (Figure 1). Finally, we note that the sequence of the type C hexokinase, PpHxk4, is more ... of the Physcomitrella hexokinases We proceeded to study the intracel lular locations of the moss hexokinases. Sequences from the new hexokinases, e...

... that of human, mouse and other reported fish hepcidins. In liver, some cells expressed both types of hepcidins, while other cells expressed only one of them or neither of them (Fig. 6). These ... type II hepcidin of winter flounder. Both genes exist as single copies in the Japanese flounder genome. The structures, and therefore the functions, of Hep-JF1 and type II hepcid...

In addition, the second case showed typical findings of the inflammatory cell type of MFH with an ossifying matrix resulting from continuous fibroblast ... surrounding neoplastic fibroblasts in the central region of the lesion. The current report may be important in identifying MFHs based on histologic and immunohistologic fin...

Effects of zinc on cofactor binding The effects of zinc on the binding of the reduced co- factor NADPH to the enzyme, at pH 8.0, in the pres- ence or absence of glutamate were examined using fluorescence ... part of the $ 18° movement of the NAD binding domain during catalysis [30,31]. Therefore it is possible that zinc, binding here, could mimic the effects o...
