Modulation of p53 binding to MDM2: computational studies reveal important roles of Tyr100.

Methods The 'open' state of MDM2 (residues 25-109) was obtained from the crystal structure of the MDM2-p53 complex (RCSB entry 1YCR , resolved at 2.6 Å) [ 10 ].

Figure 1 MDM2 in surface representation, taken from various structures available in PDB, complexed with various ligands including WT p53 ( 1YCR ), a β-hairpin peptide ( 2AXI ), small molecule 'nutlin' ( 1RV1 ), an 8-mer p53 peptide analogue ( 2GV2 ), an optimized peptide ( 1T4F ) and a 12 residue peptide .

We have used molecular dynamics simulations to examine three different conformations of MDM2: (i) 'Open' state of the conformation taken from the wild type (WT) complex ( 1YCR ) with the Y100 side chain pointing away from the binding pocket; (ii) 'closed' state - the conformation of MDM2 taken from the complex with α-helical P27S mutant of p53 with the Y100 side chain pointing towards the binding pocket; (iii) The 'apo' state - the unliganded state of MDM2, obtained from the ensemble of NMR structures [ 8 ] where Y100 is in a deeply buried position (see Figure 2 ).

Both, the crystal structure (PDB code 1YCR ) [ 10 ] and molecular dynamics (MD) simulations of the complex of MDM2 and a 13 residue fragment of the transactivation domain of p53 show that Y100 points away from the binding pocket and forms a hydrogen bond (HB) with either the backbones of E28 or N29 of wild type (WT) p53 peptide.

If the p53 peptide is extended at its C-terminus (as seen in the crystal structure 1YCR ), the side chain hydroxyl of Y100 is involved in hydrogen bond (HB) with the backbone of either E28 or N29 of the p53 peptide; however the p53 peptide can also adopt an α-helical conformation at its C-terminus and this is potentiated by the Y100 hydroxyl forming an HB with the backbone of L26 which provides a 'cozier' fit between the p53 peptide and MDM2 [ 7 ].

For this, residues 19-24 of HDM2 were crafted from 4ERF resolved at 2.0Å [ 39 ] on to 1YCR, so as the initial structure includes residues 19 -109 of HDM2.

In order to examine the dynamics of the full N-terminal region of HDM2 we grafted 11 conformations of the lid (residues 1-24) from the ensemble of NMR structures (1Z1M)[ 37 ] onto 1YCR (residues 25-109).

In addition, there is a recent crystal structure of HDM2 (residues 6-109) that has become available (in complex with a small molecule; PDB code 4HBM, resolved at 1.9Å)[ 38 ] with an ordered lid and so we also created a 12 th structure of 1YCR where we grafted this lid (only from residues 6-24).
