In bacteria, the RNA polymerase (RNAP) holoenzyme binds and unwinds promoter DNA, forming the transcription bubble of the open promoter complex (RPo). We have determined crystal structures, refined to 4.14 Å-resolution, of RPo containing Thermus aquaticus RNAP holoenzyme and promoter DNA that includes the full transcription bubble. RNA polymerase - Wikipedia A sigma (σ) factor binds to the core, forming the holoenzyme. After transcription starts, the factor can unbind and let the core enzyme proceed with its work. The core RNA polymerase complex forms a "crab claw" or "clamp-jaw" structure with an internal channel running along the full length.

In the holoenzyme complex th with core enzyme, r70 binds the -35 and -10 elements of the ifi predominant class of bacterial promoters: region 4 of a70 rec- ar ognizes the -35 element (1, 2) as double-stranded (ds)DNA, and B, region 2 of o'70 recognizes the -10 element as both dsDNA and to single-stranded (ss)DNA (2-6). Holoenzyme - The School of Biomedical Sciences Wiki Holoenzyme is a catalytically active enzyme that consists of apoenzyme and cofactor. Cofactors can make reactions that cannot be done by standard twenty amino acids. Cofactors are divided in two groups: metals ( Zn 2+, Mg 2+, Ni 2+ , Mo, Se, Mn, K + ), coenzymes . Use of the same coenzyme usually means that enzymes catalyse similar mechanisms . Crystal structure of the 500-kDa yeast acetyl-CoA ...

DNA Polymerase III Holoenzyme - an overview ... The holoenzyme comprises two dimerized β subunits (β 4 ), a dimeric core Pol III (α 2 ε 2 θ 2) and a single γ complex (γ 1 τ 2 δ 1 δ′ 1 χ 1 ψ 1) that loads the β processivity clamp onto the DNA template. The physical and genetic evidence supporting dimerization of DNA polymerase III fits nicely with a structural model for replication.

Crystal structure of the α6β6 holoenzyme of propionyl ... The structure of the α6β6PCC holoenzyme contains a central β6hexamer core, in the shape of a short cylinder with a small hole along its axis (Fig. 1a). This hexameric core can be considered as a trimer of β2dimers, with each dimer being formed by one subunit from each layer of the structure (Fig. 1b).

Enzymes - Structure, Classification, and Function Enzymes are a linear chain of amino acids, which give rise to a three-dimensional structure. The sequence of amino acids specifies the structure, which in turn identifies the catalytic activity of the enzyme. Upon heating, enzyme's structure denatures, resulting in a loss of enzyme activity, that typically is associated with temperature.
