31120181-1	2019	The mechanisms of the thermal reactions of the two iconic magnesium oxide cations MgO.+ and Mg2 O2 .+ with methane have been re-evaluated at the CCSD(T)/CBS//CCSD/def2-TZVP level of theory.	Methane	107-114	cystathionine beta-synthase	Homo sapiens	153-156	
18167585-4	2007	For the methane dimer, errors for SCS(N)-(L)MP2/CBS remain in the 0.2-0.3 kcal mol(-1) range, corresponding to a larger relative error of 40-50%.	Methane	8-15	cystathionine beta-synthase	Homo sapiens	48-51
