We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

SOLUTION STRUCTURE OF RNA POLYMERASE SUBUNIT H

Overview

The archaeal H and eukaryotic RPB5 RNA polymerase subunits are highly, homologous and are likely to play a fundamental role in transcription that, extends from archaea to humans. We report the structure of subunit H, in, solution, from the archaeon Methanococcus jannaschii using, multidimensional nuclear magnetic resonance. The structure reveals a novel, fold containing a four-stranded mixed beta sheet that is flanked on one, side by three short helices. The dominant feature is beta-ribbon motif, which presents a hydrophobic, basic surface, and defines a general RNA, polymerase architectural scaffold.

About this Structure

1HMJ is a Single protein structure of sequence from Methanocaldococcus jannaschii. Full crystallographic information is available from OCA.
