title: Unstable S-Adenosylmethionine synthetase in an ethionine-resistant strain of Neurospora crassa.
abstract: A pleitropic ethionine-resistant mutant of Neurospora contains an S-adenosylmethionine synthetase that is labile to heat and dialysis but exhibits normal kinetics for methionine and ethionine.
