'Molecules it Interacts With and where '

The protein binds to GDP as well as the following ligands in order to promote the attachment of the protein complex to the ribosome A site.

PHOSHOAMINOPHOSPHONIC ACID-GUANYLATE ESTER

PHENYLALANINE MAGNESIUM ION

'Origin'

It has domains that are created in yeast (phenyl-transfer RNA) , in the heat resistant Thermus aquaticus (EF-Tu elongation factor, and can be synthetically manufactured.

'Structure'

It has 3 domains. G proteins, Elongation Factors, and the EF-Tu/eEF-1alpha/eIF2-gamma C-terminal domain. It is composed of 6 chains, which combine in alignment.

Specific are highlighted here. The ligands listed above, GDP, Phe, and Mg+2 ion each attach at these locations which are still being explored.

which play a crucial role in binding to the ribosome during translation. They form positive pockets with which negative amino acids can bind to.

which play a crucial role in binding to the ribosome during translation.

'Function"

The protein complex participates in placing the amino acids in their correct order when messenger RNA is translated into a protein sequence on the ribosome by promoting GTP-dependent binding of tRNA to the A site of the ribosome. In other words, it is involved with elongation during polypeptide synthesis.

Structural highlights

GAL4 is a specific DNA complex of the 65-residue, N-terminal fragment of the yeast transcriptional activator. This protein binds as a dimer to a symmetrical 17 base-pair sequence. A small domain within this protein containing zinc recognizes a conserved CCG triplet at each end of the site through direct contact with the major groove. A short coil dimerization element imposes 2-fold symmetry. A segment of extended polypeptide chain links the metal-binding module to the dimerization element and specifies the length of the site. The complex's open structure allows for another protein to bind coordinately with GAL4.
