Figure 9.

Variation of velocity profile of the entire chain as a function of sidechain tags of different length $l_{\mathit{tag}}$. To extract the dependence of the sidechain protein tags we have subtracted the velocity of the homopolymer ($l_{\mathit{tag}}=0$). (a)–(c) correspond to $l_{\mathit{tag}}=3,4$ and 6 respectively. The increasing local variations around the position of each sidechain tag are evident. It is also worth observing that the last tag in all three cases has the same velocity of the entire chain (average velocity) and therefore, can be used as a reference velocity for the chain.
