All chaperonins mediate ATP-dependent polypeptide folding by confining substrates within a central chamber. Intriguingly, the eukaryotic chaperonin TRiC (also called CCT) uses a built-in lid to close ...

We report here the crystal structure of retinol dehydratase, an enzyme that catalyzes the synthesis of anhydroretinol. The enzyme is a member of the sulfotransferase superfamily and its crystal ...

A number of plants disperse their seeds in a rather artistic way: the seed capsules of the ice plant Delosperma nakurense, for instance, unfold lids over the seed compartments in the manner of a ...

Toyoda Gosei. has filed a patent for a lid opening/closing structure with two power-applying mechanisms for different opening/closing methods. The second mechanism engages only when an external force ...
