18391207-6	2008	IMR-90 fibroblast populations cultured in magnesium-deficient conditions had increased senescence-associated beta-galactosidase activity and increased p16(INK4a) and p21(WAF1) protein expression compared with cultures from standard media conditions.	Magnesium	42-51	galactosidase beta 1	Homo sapiens	109-127	
23931694-4	2013	Besides glucose bioassay, the amplification of calibration parameters was also studied in cascaded two-enzyme lactose biosensor, where the initial step of lactose bio-recognition, the beta-galactosidase - catalyzed lactose hydrolysis, was additionally accelerated by magnesium ions.	Magnesium	267-276	galactosidase beta 1	Homo sapiens	184-202	
1616704-0	1992	Magnesium chelation inactivates beta-galactosidase in -20 degrees C storage.	Magnesium	0-9	galactosidase beta 1	Homo sapiens	32-50	
6774745-0	1980	Comparison of the beta-galactosidase conformations induced by D-galactal and by magnesium ions.	Magnesium	80-89	galactosidase beta 1	Homo sapiens	18-36	
4721625-0	1973	The role of magnesium ions in beta-galactosidase hydrolyses.	Magnesium	12-21	galactosidase beta 1	Homo sapiens	30-48
