Example sentences for: protomer

How can you use “protomer” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In most AAA proteins, the ring structure is formed by six identical polypeptide subunits, with each contributing a single AAA protomer [ 14 ] . However, the AAA motor dynein differs in having six distinct AAA protomers disposed in tandem on a single polypeptide subunit of unusually high molecular weight, and it is believed to form a unimolecular pseudo-hexameric AAA ring [ 5 6 16 ] .

  • 4) shows that the evolutionary distance between any two protomers in a single organism is substantially greater than that between any single protomer taken from different organisms, even for such highly disparate organisms as humans and Giardia.

  • The structure of an AAA protomer includes an ATP-binding site located in the cleft between a large α/β N-subdomain and a smaller all-α C-subdomain.

  • The polypeptide joining the adjacent AAA protomers in midasin is approximately 100 residues long between all protomer pairs.

  • This basic domain organization shows a striking parallel to that of magnesium chelatase, a heterotrimeric enzyme containing BchD, BchI and BchH subunits, that performs ATP-dependent insertion of Mg 2+into the protoporphyrin IX ring in the course of chlorophyll biosynthesis [ 49 ] . In particular, the BchD subunit resembles midasin in possessing a single AAA protomer close to its NH 2 -terminus, together with a short aspartate-glutamate-rich region and a MIDAS-containing domain at its carboxy-terminus.
