Crossword Genius

US on move turning deadly (8)

Ross

I believe the answer is:

venomous

'deadly' is the definition.
('venomous' can be a synonym of 'deadly')

'us on move turning' is the wordplay.
'turning' is an anagram indicator.
'us'+'on'+'move'='usonmove'
'usonmove' with letters rearranged gives 'VENOMOUS'.

(Other definitions for venomous that I've seen before include "Poisonous like many snakes" , "Toxic - spiteful" , "(Of snake) injecting poison" , "acid" , "Extremely poisonous" .)

I've seen this clue in The Telegraph.
