Propylamine transferase

One of two novel transferases reported recently is the tetrahydromethanopterin methyltransferase involved in methanogenesis in Methanobacterium thermoautotrophicum [180]. No thermostability data on the oxygen sensitive enzyme were presented. The second enzyme is the propylamine transferase studied in the archaebacterium Sulfolobus solfataricus [181]. This enzyme (optimum pH 7.5) appears to be solely responsible for transfer of the aminopropyl residue from S-adenosyl (5 )-3-methylthiopropylamine to various acceptors.
