... located on the intact protein. Therefore, determination of the kinetics of phosphorylation of these peptides allows the order of phosphorylation of the six TCRf ITAM tyrosines, by the PTK Lck, ... Role of electrostatic interactions in SH2 domain recogni- tion: salt dependence of tyrosyl-phosphorylated peptide binding to the tandem SH2 domain of the Syk kinase and the single SH2 domain of the ... tyrosines at each time point. The level of phosphorylation was seen to increase mainly over the first 30 min, with the levels of each phosphotyrosine staying similar over the following 60 min. The...

... and so the choice of the constant level of Fru was not critical for determination of D K m (1.23 ± 0.15). The KIE data in Table 4 are instrumen- tal in delineating the kinetic mechanism of AfM1PDH and ... 3, indi- cates that NADH binds to the enzyme prior to binding of Fru6P. The absence of a KIE on k cat ⁄ K m for the substrate binding first is a clear requirement of the strictly ordered kinetic ... However, slowing the reaction by using NADD in place of NADH will further restrict the availability of enzyme–NAD + , explaining the complete lack of substrate inhibition under these con- ditions. Proposed...

... sequences contained in any of their strain members. For the 216-probe set, the minimum number of probes differentiating a DENV-1 strain from the all other strains belonging to one of the three other serotypes ... While these values contribute to the fit- ness of a set, the size of the set plays a much greater role in an effort to reduce the number of probes needed and thus the cost of the array. Therefore, ... One or more of the four serotypes of the dengue virus are endemic in many parts of the world, including all of south-east Asia, parts of Africa, and Southern and Central America. The Aedes aegypti...

Identification of nitration site in the extracellular domain of ILT2 In the extracellular domain of ILT2, there are several Tyr residues that participate in ... this is the first report of a post-translational modification of the ILT2 protein. The other member of the ILT family, LILRA4, has also been found nitrated within the domain Ig-like C2-type 4 in human ... band at 42 kDa. The data indicate the intensity of the HLA-G band related to the b-actin band and are representative of three different experiments. ILT2 nitration in the binding domain A. Dı ´ az-Lagares...

Pre-incubation of the recombinant protein with ... against inactivation was observed and the initial GS activity was maintained (116.5 ± 7.3% of the initial activity). The protective effect was abolished when the recom- binant protein was heat-inactivated ... but the binding was not affected by preincubation of the protein with FP. These results also indicate that Pf1-Cys-Prx can bind to FP at pH 7.4, which is the pH of the parasite cytosol. The fact...
