Abstract

Myosin is a molecular motor that undergoes ATP-driven conformational changes during force production and motility. The S1 fragment myosin head consists of both the globular motor domain, containing the ATP- and actin-binding sites, and the lever arm, which amplifies small conformational changes in the motor domain into larger motions by which myosin moves actin. The motor domain contains four major subdomains linked by three single-stranded joints: the N-terminal subdomain, the upper 50-kDa subdomain, the lower 50-kDa subdomain, and the C-terminal converter subdomain [PubMed11016966]. The N-terminal subdomain has an SH3-like partly opened beta barrel topology, with the last strand being interrupted by a 3-10 helical turn. The N-terminal and upper 50-kDa subdomains together form the nucleotide-binding pocket. The binding of specific nucleotides alters the structural state of the myosin head during the contractile cycle.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 6 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Myosin S1 fragment, N-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 6 hidden Markov models representing the Myosin S1 fragment, N-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
