: second step of two-step reaction (see R09720, R03444+R04371)
: Requires a CPD-7 for activity. In contrast to EC 4.2.1.36, ENZRXN-7008, this enzyme can catalyze both the dehydration of HOMO-CIT to form HOMO-CIS-ACONITATE and the subsequent hydration reaction that forms HOMO-I-CIT. In addition to HOMO-CIS-ACONITATE, the enzyme can also catalyze the hydration of the physiological substrates CPD-152 and CPD-301 as well as the non-physiological substrate CPD-10749. CIS-ACONITATE, THREO-DS-ISO-CITRATE and CPD-10745 cannot act as substrates, and CPD-150 and CPD-149 act as inhibitors of the enzyme [18765671].
