[ccp4bb] 2 ligands/monomer

2014-03-03 Thread Wei Shi
Dear all, Does anyone happen to know examples of 2 ligands bind to a single protein / each monomer protein in 2 different ligand binding pockets? I know the following example: (1). phosphofructokinase, which binds ATP as both a ligand and a feedback inhibitor in different sites (2). 2 cAMP bound t

Dear Wei, The enzyme ribonucleotide reductase can, depending on organism and class, bind ATP as a substrate in the active site (c), as an allosteric regulator of substrate specificity at another site (s) and as an overall activity regulator at a third site (a)! It can also bind dATP at the seco

Hi, Another example is the Shiga-like toxin B-subunit pentamer (i.e. the cell-surface binding component of this A-B toxin), which binds 3 Gb3 trisaccharides per monomer: http://pdbe.org/1bos http://www.ncbi.nlm.nih.gov/pubmed/9485303 Best wishes, Randy Read On 4 Mar 2014, at 10:41, Derek Log
