Table schema:
CREATE TABLE enzyme (id VARCHAR, name VARCHAR); CREATE TABLE medicine (id VARCHAR, name VARCHAR); CREATE TABLE medicine_enzyme_interaction (interaction_type VARCHAR, medicine_id VARCHAR, enzyme_id VARCHAR)

Question: What is the interaction type of the enzyme named 'ALA synthase' and the medicine named 'Aripiprazole'?
SQL: SELECT T1.interaction_type FROM medicine_enzyme_interaction AS T1 JOIN medicine AS T2 ON T1.medicine_id = T2.id JOIN enzyme AS T3 ON T1.enzyme_id = T3.id WHERE T3.name = 'ALA synthase' AND T2.name = 'Aripiprazole'
