1. Domain arrangements in the Protein a-transducin

Crystal structure of a-transducin. Domain identification in a-transducin by clustering secondary structures.
   
Identified domains in a -transducin ( N terminal discontinuous GTP-binding domain with the classical doubly-wound fold and a helix-rich insertion domain).

 

2. Clustering of domains

Structural similarities of 428 domains.
   

Structure of proteins in the G-protein (ras) superfamily. Domain definition by DIAL and SCOP.

 

3. Model of the tetrameric arrangement of the transmembrane domain of inositol-triphosphate receptor

Model of the tetrameric arrangement of the transmembrane domain of inositol-triphosphate receptor. The model of the individual protomers have been obtained from the coordinates of the potassium channel (Doyle et al., 1998).

5. Models of members of bioluminescence superfamily - EagI model compared with LasI model

Models of members of bioluminescence superfamily - EagI model compared with LasI model. SAM and the corresponding PNT substrate have been docked and shown inball-and-stick form.Hydrophobic residues are shown in white, acidic residues in red and basic residues in blue.The PNT-binding site of LasI is broader and is acidic.

6. Three-dimensional model of Bdm1 obtained by threading the sequence on the fold of BPHD

Three-dimensional model of Bdm1 obtained by threading the sequence on the fold of BPHD (pdbcode: 1c4x ) . Side-chains of three residues (His164, Ser259 and Asp231, identified by the functional template approach) shown qualify the criteria for the catalytic triad of alpha/beta hydrolases.
