A distinct group, called bridge-like lipid-transport proteins (BLTPs), may support bulk lipid transfer by forming long, tunnel-like structures that span between organelles. Structural analysis of ...

The properties of biological materials like proteins and nucleic acids are largely determined by their primary sequence. Certain segments in the sequence strongly influence specific functions, but ...

and proteins essential to normal biological function. The procedures presented in this paper allow structure determination at atomic resolution without ever removing the proteins from their membrane ...
