Taken to be part of Bristol enterprise (6)
I believe the answer is:
stolen
'taken' is the definition.
(similar in meaning)
'part of bristol enterprise' is the wordplay.
'part of' says the answer is hidden in the clue.
'STOLEN' is hidden in the letters of 'bristol enterprise'.
'to be' acts as a link.
(Other definitions for stolen that I've seen before include "Filched" , "Taken without right" , "Pinched" , "plagiarised?" , "Nicked" .)
