1d8d Summary



The structure was published by Long, S.B., Casey, P.J., and Beese, L.S., in 2000 in a paper entitled "The basis for K-Ras4B binding specificity to protein farnesyltransferase revealed by 2 A resolution ternary complex structures." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1999.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely farnesyltransferase (alpha subunit), farnesyltransferase (beta subunit), and K-RAS4B PEPTIDE SUBSTRATE.

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 heterotrimers.
