Phosphate acetyltransferase, partial; 3'-end; In Escherichia coli, a truncated version of this gene has been produced, observing that only C-terminal domain is needed for the catalytic activity. Also, folding and regulation were preserved in all truncated proteins.

Elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF-2 subfamily.

DNA polymerase I, partial; Shortened 3'-end; Almost-intact 5'-3' exonuclease domain; lacking both 3'-5' exonuclease domain and Klenow fragment, this last one includes the region in charge of polymerase activity.

Pimeloyl-[acyl-carrier protein] methyl ester esterase.

Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

Methionine--tRNA ligase; Shortened 3'-end; By generating mutants with shortened 3'-ends of the E.coli's metG gene, it was established that the first 547 residues was the shortest size able to maintain the polypeptide as a functional and stable structure; Belongs to the class-I aminoacyl-tRNA synthetase family.

Ornithine carbamoyltransferase chain I.

Bifunctional aspartokinase/homoserine dehydrogenase 1; In the C-terminal section; belongs to the homoserine dehydrogenase family.
