Common fold in helix-hairpin-helix proteins.
Helix-hairpin-helix (HhH) is a widespread motif involved in non-sequence-specific DNA binding. The majority of HhH motifs function as DNA-binding modules, however, some of them are used to mediate protein-protein interactions or have acquired enzymatic activity by incorporating catalytic residues (DNA glycosylases). From sequence and structural analysis of HhH-containing proteins we conclude th...
متن کاملHelix-bundle membrane protein fold templates.
In the fold recognition approach to structure prediction, a sequence is tested for compatibility with an already known fold. For membrane proteins, however, few folds have been determined experimentally. Here the feasibility of computing the vast majority of likely membrane protein folds is tested. The results indicate that conformation space can be effectively sampled for small numbers of heli...
متن کاملn-fold Commutative Hyper K-ideals
In this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper K-ideals. These definitions are thegeneralizations of the definitions of commutative, andimplicative hyper K-ideals, respectively, which have been definedin [12]. Then we obtain some related results. In particular wedetermine the relationships between n-fold implicative hyperK-ideal and n-fol...
متن کاملAgrobacterium tumefaciens VirC2 enhances T-DNA transfer and virulence through its C-terminal ribbon-helix-helix DNA-binding fold.
Agrobacterium tumefaciens VirC2 stimulates processing of single-stranded T-DNA that is translocated into plants to induce tumor formation, but how VirC2 functions is unclear. Here, we report the 1.7-A X-ray crystal structure of its trypsin-resistant C-terminal domain, VirC2(82-202), which reveals a form of the ribbon-helix-helix (RHH) DNA-binding fold contained within a single polypeptide chain...
متن کاملFold me or leave me
he only confirmed mechanism for protein-mediated membrane fusion involves the formation of helix bundles, in which helices attached to two membranes pack against one another to draw together the membranes. In the final fused state, six-helix bundles are formed by HIV Env and paramyxovirus F proteins, members of the class I group of viral fusion proteins. Although the class I founding member, in...
