Protein blocks

Protein blocks are structural prototypes defined by de Brevern et al. [1] (see also references [2] & [3]). Their main interest is to modelize a 3-dimension local structure into a 1-dimension sequence. In principle, any conformation of any amino acid could be represented by one of the sixteen available protein blocks …

Ambient occlusion-like with PyMOL

QuteMol allows production of nice realistic molecular pictures. PyMOL could do similar things albeit results are not strictly equivalent. Here is an example taken from the PyMOL wiki that produced the picture above.
