B [auth L]PF01510N-acetylmuramoyl-L-alanine amidase (Amidase_2)N-acetylmuramoyl-L-alanine amidaseThis family includes zinc amidases that have N-acetylmuramoyl-L-alanine amidase activity EC:3.5.1.28. This enzyme domain cleaves the amide bond between N-acetylmuramoyl and L-amino acids in bacterial cell walls (preferentially: D-lactyl-L-Ala). The ...This family includes zinc amidases that have N-acetylmuramoyl-L-alanine amidase activity EC:3.5.1.28. This enzyme domain cleaves the amide bond between N-acetylmuramoyl and L-amino acids in bacterial cell walls (preferentially: D-lactyl-L-Ala). The structure is known for the bacteriophage T7 structure and shows that two of the conserved histidines are zinc binding.

This domain has a role in interaction with regions of upstream promoter DNA and the nascent RNA chain, leading to the processivity of the enzyme [1]. In order to make mRNA transcripts the ...This is the N-terminal domain of DNA-directed RNA polymerase. This domain has a role in interaction with regions of upstream promoter DNA and the nascent RNA chain, leading to the processivity of the enzyme [1]. In order to make mRNA transcripts the RNA polymerase undergoes a transition from the initiation phase (which only makes short fragments of RNA) to an elongation phase. This domain undergoes a structural change in the transition from initiation to elongation phase. The structural change results in abolition of the promoter binding site, creation of a channel accommodating the heteroduplex in the active site and formation of an exit tunnel which the RNA transcript passes through after peeling off the heteroduplex [2].
