Suffer side-effects from touching performance (5)
I believe the answer is:
react
'suffer side-effects' is the definition.
(eg having an allergic reaction)
'touching performance' is the wordplay.
'touching' becomes 're' (re can mean touching or regarding).
'performance' becomes 'act' (act is a kind of performance).
're'+'act'='REACT'
'from' is the link.
(Other definitions for react that I've seen before include "Acknowledge" , "Respond emotionally" , "Behave in response" , "Trace (anag)" , "Act as opponent" .)
