Differential regulation of glutamatecysteine ligase subunit expression and increased holoenzyme formation in response to cysteine
In the in-silico three dimensional (3D) model of pneumolysin (PLY), cysteine
of this conserved region is present at position 428 and is in hydrophobic contact with Ala 373 and Trp 436 of the conserved region.

, as the first organic reduced sulfur compound, and methionine and its derivatives contribute to life not only as building blocks in proteins and their activity, but also as precursors for the synthesis of glutathione (GSH), cofactors (like Fe-S clusters, heme, siroheme, molybdenum centres, and lipoic acid), essential vitamins (biotin and thiamine), sulfur esters (coenzyme A), and sulfur derivatives.
