In a previous post, I tried to explain what are proteins blocks (PBs). For those who forgot, PBs are structural prototypes used to modelize a 3D local protein structure into a 1D sequence. I illustrated this with a picture of protein blocks that I also posted on Flickr.

I initially …

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 …
