Helix Interaction Tool (HIT): a web-based tool for analysis of helix-helix interactions in proteins
MOTIVATION In many proteins, helix-helix interactions can be critical to establishing protein conformation (folding) and dynamics, as well as determining associations between protein units. However, the determination of a set of rules that guide helix-helix interaction has been elusive. In order to gain further insight into the helix-helix interface, we have developed a comprehensive package of...
متن کاملPredicting helix–helix interactions from residue contacts in membrane proteins
MOTIVATION Helix-helix interactions play a critical role in the structure assembly, stability and function of membrane proteins. On the molecular level, the interactions are mediated by one or more residue contacts. Although previous studies focused on helix-packing patterns and sequence motifs, few of them developed methods specifically for contact prediction. RESULTS We present a new hierar...
متن کاملID helix-loop-helix proteins
The helix-loop-helix (HLH) family of transcription factors comprises >200 members, which have been identified in organisms from yeast to man (reviewed in Littlewood and Evan, 1995; Massari and Murre, 2000). In metazoa, HLH proteins function in the coordinate regulation of gene expression, orchestrating cell cycle control, cell lineage commitment and cell differentiation. An essential role has b...

متن کاملCommon 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...
