1gpj Summary



The structure was published by Moser, J., Schubert, W.-D., Beier, V., Bringemeier, I., Jahn, D., and Heinz, D.W., in 2001 in a paper entitled "V-Shaped Structure of Glutamyl-tRNA Reductase, the First Enzyme of tRNA-Dependent Tetrapyrrole Biosynthesis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of GLUTAMYL-TRNA REDUCTASE. This molecule has the UniProt identifier Q9UXR8 (HEM1_METKA)search. The sample contained 404 residues which is 100% of the natural sequence. Out of 404 residues 398 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
