RPSBLAST alignment for GI: 254780143 and conserved domain: cd00653

>gnl|CDD|73223 cd00653, RNA_pol_B_RPB2, RNA polymerase beta subunit. RNA polymerases catalyse the DNA dependent polymerization of RNA. Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial. and chloroplast polymerases). Each RNA polymerase complex contains two related members of this family, in each case they are the two largest subunits.The clamp is a mobile structure that grips DNA during elongation.. Length = 866

 Score =  107 bits (270), Expect = 1e-23
 Identities = 63/223 (28%), Positives = 99/223 (44%), Gaps = 64/223 (28%)
