For several decades, the presence of knots in naturally-occurring proteins was
largely ruled out a priori for its supposed incompatibility with the efficiency
and robustness of folding processes. For this very same reason, the later
discovery of several unrelated families of knotted proteins motivated researchers
to look into the physico-chemical mechanisms governing the concerted sequence of
folding steps leading to the consistent formation of the same knot type in the
same protein location. Besides experiments, computational studies are providing
considerable insight into these mechanisms. Here, we revisit a number of such
recent investigations within a common conceptual and methodological framework. By
considering studies employing protein models with different structural resolution
(coarse-grained or atomistic) and various force fields (from pure native-centric
to realistic atomistic ones), we focus on the role of native and non-native
interactions. For various unrelated instances of knotted proteins, non-native
interactions are shown to be very important for favoring the emergence of
conformations primed for successful self-knotting events.
