FunFam 5255: Translation factor GUF1, mitochondrial

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Elongation factor 4. [EC: 3.6.5.n1]
GTP + H(2)O = GDP + phosphate.
  • The enzyme is required for accurate and efficient protein synthesis under certain stress conditions.
  • May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes.
  • Back-translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly.
  • Binds to ribosomes in a GTP-dependent manner.

DNA-directed RNA polymerase. [EC: 2.7.7.6]
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
  • Catalyzes DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time.
  • Can initiate a chain de novo.
  • In eukaryotes three forms of the enzyme have been distinguished on the basis of sensitivity of alpha-amanitin, and the type of RNA synthesized.
  • See also EC 2.7.7.19 and EC 2.7.7.48.
