The 13 C NMR (100 MHz, D 2 O) revealed resonances at C = 23.75 (CH 2 S), 24.30 (CH 2 , C-3), 29.26 (CH 2 , C-4), 31.52 (NHCH 3 ), 41.33 (CH 2 , C-10), 56.09 (CH, C-2), 62.06 (CH, C-7), 167.58 (C=O, C-5 and C-8), and 172.86 (C=O, C-1 and C-11)
CBS selectively replenishes the GSH levels under cystine-restricted conditions Multiple critical enzymes are involved in the normal function of the TSS pathway, including CBS and CSE, which catalyze the first two steps of de novo cysteine generation, from homocysteine to cystathionine and then cysteine
