34524348-4	2021	1H NMR monitoring showed that these compounds are very resistant to UV (lambda = 365 nm) or sunlight irradiation and do not undergo photodegradation with a loss of antiproliferative activity that is inherent in heterocyclic analogues of CA-4.	Hydrogen	0-2	carbonic anhydrase 4	Homo sapiens	237-241	
11834591-6	2002	In the HS group, a small decrease in EAAT1-immunoreactivity (IR) was observed in CA4 and in the polymorphic and supragranular layer of the dentate gyrus, compared with the control group.	Hydrogen	7-9	carbonic anhydrase 4	Homo sapiens	81-84	
30446621-9	2019	Further analysis of the CAIV-binding site revealed that the His-88 in CAIV can either act as H donor or H acceptor for the hydrogen bond, depending on the charge of the binding residue in the chaperone.	Hydrogen	123-131	carbonic anhydrase 4	Homo sapiens	24-28	
31476557-3	2019	Various residues capable of forming hydrogen bonds as well as salt bridges were placed in this pocket via a carboxamides linkage, which led to drastic improvement of potency and selectivity towards hCA IV.	Hydrogen	36-44	carbonic anhydrase 4	Homo sapiens	198-204	
33276663-3	2020	On the other hand, an anhydride CA4 formed a dimer by hydrogen bonds between adjacent molecules in the crystal, which were aggregated by van der Waals forces and placed in parallel planar cyclic sites.	Hydrogen	54-62	carbonic anhydrase 4	Homo sapiens	32-35	
30446621-9	2019	Further analysis of the CAIV-binding site revealed that the His-88 in CAIV can either act as H donor or H acceptor for the hydrogen bond, depending on the charge of the binding residue in the chaperone.	Hydrogen	123-131	carbonic anhydrase 4	Homo sapiens	70-74
