Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE medicine ( id number, name text, trade_name text, fda_approved text )
TABLE: CREATE TABLE medicine_enzyme_interaction ( enzyme_id number, medicine_id number, interaction_type text )
TABLE: CREATE TABLE enzyme ( id number, name text, location text, product text, chromosome text, omim number, porphyria text )

### Question ###
What is the id and name of the enzyme with most number of medicines that can interact as 'activator'?

### Accurate SQL ###

SELECT T1.id, T1.name FROM enzyme AS T1 JOIN medicine_enzyme_interaction AS T2 ON T1.id = T2.enzyme_id WHERE T2.interaction_type = 'activitor' GROUP BY T1.id ORDER BY COUNT(*) DESC LIMIT 1
