1.4.1.B6	secondary amine dehydrogenase	deleted, replaced by EC 1.4.1.28	
1.4.3.6	amine oxidase (copper-containing)	deleted, this was classified on the basis of cofactor content rather than reaction catalysed and is now known to contain two distinct enzyme activities. It has been replaced by two enzymes, EC 1.4.3.21 (primary-amine oxidase) and EC 1.4.3.22 (diamine oxidase)
