Coy nurse as the centre of attraction (8)

I believe the answer is:

cynosure

I'm a little stuck... Click here to teach me more about this clue!

'the centre of attraction' is the definition.
(I've seen this before)

'coy nurse' is the wordplay.
'coy nurse' anagrams to 'CYNOSURE'.
But, I'm not sure how the anagram is indicated.

'as' is the link.

Can you help me to learn more?

(Other definitions for cynosure that I've seen before include "Little Bear" , "major attraction" , "Centre of attention" , "Focus of attention" , "Centre of attraction" .)

I've seen this clue in The Globe and Mail.
