7.2.1.3	acetylation	the N-terminus of isozyme CBCytB is anchored to the membrane by acetylation of the amino-terminal Met residue	744757	
7.2.1.3	additional information	the N-terminal Met residue is removed posttranslationally. No partial proteolytic digestion at the C-terminal part of wild-type Zmb561	744309	
7.2.1.3	no glycoprotein	although the deduced amino acid sequence of Zmb561 contains two potential N-glycosylation sites (109NES111 and 203NFT205), periodic acid-Schiff staining of the purified wild-type-Zmb561 in SDS-PAGE gels do not show any indication of glycosyl groups	744309
