32061854-0	2020	Characterization of Cu2+ and Zn2+ binding sites in SUMO1 and its impact on protein stability.	Zinc	29-33	small ubiquitin like modifier 1	Homo sapiens	51-56	
32061854-4	2020	Between Cu2+ and Zn2+, the former binds more strongly with SUMO1 as determined using fluorescence spectroscopy.	Zinc	17-21	small ubiquitin like modifier 1	Homo sapiens	59-64	
32061854-7	2020	Cu2+ induced paramagnetic quenching and Zn2+ induced chemical shift perturbation of 15N-1H cross-peaks were used to identify their respective binding sites in SUMO1.	Zinc	40-43	small ubiquitin like modifier 1	Homo sapiens	159-164	
32061854-9	2020	Our findings provide structural insights into the SUMO1-Cu2+/Zn2+ interaction, and its impact on aggregation of SUMO1 which might affect its ability to modify functions of target proteins.	Zinc	61-64	small ubiquitin like modifier 1	Homo sapiens	50-55
