This protein hydrolyzes DNA adjacent to the 5′-end of an apurinic/apyrimidinic (AP) site to produce a nick with a 3′-hydroxyl group and a 5′-deoxyribose phosphate moiety or activates the DNA-binding activity of certain transcription factors through its redox function.
The observed increased binding activity of the T397A mutation (Fig. 8K), might be a result of the removal of certain structure constraint due to the bigger "bump" of T397 in the wild type, which was replaced with a smaller alanine in the mutant.
Furthermore, the DNA binding activity of c-Myb was studied.
The erythrocyte binding activity of rPfRH240 was also studied in similar erythrocyte binding assays.
Binding activity of dust samples.
In the case of Cyt2Aa toxin it was shown that insertion of a peptide sequence with aphid APN binding activity in certain loop regions resulted in Cyt2Aa toxins with aphid toxicity (Chougule et al. 2012).
Interestingly, although binding of HBPRNase3 32 41) was severely impaired in CHO-pgsD677 cells which had no HS but expressed 3-fold more CS than wild-type CHO-K1 cells, residual cellular binding activities of HBPRNase3 32 41) to CHO-pgsD677 and CHO-pgsA745 cells strongly implied that HBPRNase3 32 41) possessed certain interaction to cell surface CS.
Moreover, this variant of immobilization of SPA improves the IgG-binding activity of SPA as well as further antigen-binding activity of antibody molecules immobilized through SPA [24].
Notably, it has been reported that p300 can reduce the transcriptional activity of certain DNA-binding transcription factors [48], [49], and it will be interesting to identify these element(s) and their associated proteins in future studies.
GAF domains regulate the catalytic activity of certain vertebrate cyclic nucleotide phosphodiesterases (PDEs) by allosteric, noncatalytic binding of cyclic nucleotides.
Microgravity has been shown to influence the expression of ABC (ATP-Binding Cassette) transporters in bacteria, fungi and mammals, but also to modify the activity of certain cellular components with structural and functional similarities to ABC transporters.
