WebFeb 27, 2004 · Step 1a: Predicted hydrolysis of the phosphoamide bond in NTD of Rnl2. Nucleotidyl transferases share the same basic mechanism, which in the case of RNA ligase begins when a molecule of ATP is attacked by a nucleophilic lysine, adenylating the enzyme and releasing pyrophosphate ( Figure 1B; step 1). WebIt was found that within complex I the phosphate-protein bond is hydrolyzed at alkaline values of pH (11.0 and 13.0); at acidic pH values this bond is hydrolyzed by 50%. Within complex II the phosphate-protein bond is hydrolyzed at acidic pH values and is stable at alkaline pH values.
