Cystathionine γ-lyase是什么
WebCystathionine beta-lyase is a tetramer composed of identical subunits, and is constructed as a dimer of dimers, each associated with one molecule of PLP bound to the catalytic site by a lysine residue. [6] [8] The dimer is formed by two monomers associated through several electrostatic, hydrogen bonding, and hydrophobic interactions, whereas ...
