1959444-2	1991	A hapten containing a benzyl ammonium group was used to elicit a specific base, a carboxylate, in the combining site of an antibody that catalysed a beta-elimination reaction.	carboxylate	82-93	amyloid beta precursor protein	Homo sapiens	147-153	
15964569-1	2005	The strong pH dependence of A beta oligomerization could arise from favorable intermolecular charge-charge interactions between His and carboxylate groups, or, alternatively, by mutual electrostatic repulsion of peptide molecules.	carboxylate	136-147	amyloid beta precursor protein	Homo sapiens	28-34	
12473188-11	2002	NMR analysis showed that deprotonation of the C-terminal carboxylate group in A beta(12-24) triggered the aggregate formation, and the transition from a random coil to a beta-conformation in the C-terminal region of V18-V24 was detected on analysis of the (3)Ja(N) coupling constant in the pH range of 2.2 to 3.0.	carboxylate	57-68	amyloid beta precursor protein	Homo sapiens	78-84	
7823029-2	1994	For aspartate, the unbalanced position of its amino group between a pair of carboxylates allows its occasional biorecognition as a beta-rather than as an alpha-amino acid, whereas for proline and its homologs, their cyclic arrangement may allow the imino group, without its being replicated, to be sensed analogously as falling at either of two distances from the single carboxylate group.	carboxylate	76-87	amyloid beta precursor protein	Homo sapiens	129-135	
33802596-0	2021	Swapping the Positions in a Cross-Strand Lateral Ion-Pairing Interaction between Ammonium- and Carboxylate-Containing Residues in a beta-Hairpin.	carboxylate	95-106	amyloid beta precursor protein	Homo sapiens	130-136	
33802596-3	2021	Herein, we swapped the position of ammonium- and carboxylate-containing residues with different side-chain lengths in a cross-strand lateral ion-pairing interaction in a beta-hairpin.	carboxylate	49-60	amyloid beta precursor protein	Homo sapiens	168-174	
2922053-5	1989	The antibody-catalysed reaction, a beta-elimination reaction, exhibits saturation kinetics, substrate specificity, competitive inhibition by hapten, and specific inactivation by a reagent that modifies carboxylate residues.	carboxylate	202-213	amyloid beta precursor protein	Homo sapiens	33-39	
30637529-5	2019	We find a pronounced difference on the molecular level in the interaction behavior with free carboxylate groups of the Abeta oligomer: Li+ forms stable bridged interactions, whereas K+ interacts more transiently and lacks bridging.	carboxylate	93-104	amyloid beta precursor protein	Homo sapiens	119-124
