This page suggests molecules or topics for future articles in Proteopedia.
Suggestions by Eric Martz
These suggestions are by User:Eric Martz, who invites anyone to start articles on these molecules. In cases where morphs can be done, Eric will be happy to provide technical help.
- 2012, January:
- Krishnamurthy H, Gouaux E. X-ray structures of LeuT in substrate-free outward-open and apo inward-open states. Nature. 2012 Jan 9. doi: 10.1038/nature10737. PMID:22230955 doi:10.1038/nature10737
- LeuT is a bacterial homolog of neurotransmitter sodium symporters that remove neurotransmitters from the synapse and terminate neurotransmission. New structures presented in this paper "establish a structural framework for the mechanism of neurotransmitter sodium symporters and their modulation by therapeutic and illicit substances".
- A new substrate-free structure is outward-open, 3tt1. Comparison with a previous substrate-bound, outward occluded structure shows "how the binding of substrate closes the extracellular gate through local conformational changes".
- A new substrate-free inward-open structure, 3tt3, involves large scale conformational changes.
- The authors provide a supplementary true movie containing two morphs between three structures: substrate-free outward-open 3tt1 to leucine-bound, outward-occluded 2a65, and then to the inward-open 3tt3. Interactive morphs in Jmol could be advantageous.
- 2011, September:
- Hansen SB, Tao X, Mackinnon R. Structural basis of PIP(2) activation of the classical inward rectifier K(+) channel Kir2.2. Nature. 2011 Aug 28. doi: 10.1038/nature10370. PMID:21874019 doi:10.1038/nature10370
- "On PIP2 binding, a flexible expansion linker contracts to a compact helical structure, the cytoplasmic domain translates 6 Å and becomes tethered to the trans-membrane domain and the innner helix gate begins to open."
- Probably suitable for a morph. The apo structure is 3jyc, and the PIP2-bound structure, 3spi. Supplementary information does not include any movies.
