This molecule is recycled in a process known as abortive initiation, and aspartate side chains bind to magnesium cations to coordinate phosphates in this enzyme's catalytic product.
The omega chain of the bacterial version of this protein acts as a protective unit, restoring the entire protein if it is denatured. One type of molecular sequence influences this protein by inducing the accessory protein nusA to bind to a stem-loop rich in C-G pairs and cause the larger protein to pause. That process is known as intrinsic or rho-independent termination and is aided by riboswitches. This molecule is recycled in a process known as abortive initiation, and aspartate side chains bind to magnesium cations to coordinate phosphates in this enzyme's catalytic product. In addition to its four standard subunits, this enzyme requires another chain which increases specificity of this protein for promoter regions, known as the sigma factor. This enzyme breaks hydrogen bonds between nucleotides, producing a copy of an existing DNA molecule. For 10 points, name this molecule key to the process of transcription that forms a complementary single-stranded macromolecule.
