The isopenicillin N acyltransferases (IATs) ofAspergillus nidulansandPenicilliumchrysogenumdiffered in their ability to maintain the 40-kDa proacyltransferaseabheterodimer in an undissociated form. The native A. nidulansIAT exhibited a molecular mass of 40 kDa by gel filtration. The P. chrysogenumIATshowedamolecularmassof 29 kDaby gel filtration (corresponding to the b subunit of the enzyme) but the undissociated 40-kDa heterodimer was never observed even in crude extracts.
