PF16805 | Phage late-transcription coactivator (Trans_coact) | Phage late-transcription coactivator | This family of proteins is found in Caudovirales. It is a late-transcription coactivator which interacts with the host RNA polymerase forming a part of the initiation complex [1]. | Domain | |
PF00562 | RNA polymerase Rpb2, domain 6 (RNA_pol_Rpb2_6) | RNA polymerase Rpb2, domain 6 | RNA polymerases catalyse the DNA dependent polymerisation of RNA. Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial. and chloroplast polymerases). This domain represents the hybrid binding domain ... | Domain |
