aAb PA or a functionalized linker (* stands for two different linker-functional groups) that can react covalently through a β-lactam (L) function with reactive lysine residues in the aldolase Ab binding sites yielding cpAb, cp-bsAb, and cpAb intermediates. CpAb intermediates further react with compounds (comp1/2) affording a cpAb or cp-bsAb. Linkers and Ab PAs can also react with Ab through the β-diketone (DK) or vinylketone (VK) function. (Ab, antibody. PA, programming agent: a compound fully functionalized with lactam, vinyl ketone, or diketone linker. LNK, linker. FG, functional group.).
