Introduction

Nowadays there are numerous programs for visualization of biomacromolecules in three dimensions. Except dynamical and arbitrary stylized rendering of macromolecules, they often offer additional functions like computation and graphical interpretation of various physic-chemical properties.

Task no. 1

Search out entry for human hemoglobin (2HHB) in PDB (part of SRS).

Then try to determine:

1. what experimental method was applied to determination of 3D structur
2. what is the resolution of the 3D structure
3. when was the entry submitted to the database (year)
4. how many separate polypeptide chains are comprised in this entry
5. what is the PMID of the primary cited article
6. how many related articles are refered to this article
7. finally send the image of the 3D structure of this protein
