Function

[HUTP_BACSU] Antiterminator that binds to cis-acting regulatory sequences on the mRNA in the presence of histidine, thereby suppressing transcription termination and activating the hut operon for histidine utilization.[HAMAP-Rule:MF_00779]

Evolutionary Conservation

Publication Abstract from PubMed

HutP regulates the expression of the hut structural genes of Bacillus subtilis by an anti-termination mechanism and requires two components, Mg2+ ions and L-histidine. HutP recognizes three UAG triplet units, separated by four non-conserved nucleotides on the terminator region. Here we report the 1.60-A resolution crystal structure of the quaternary complex (HutP-L-histidine-Mg2+-21-base single-stranded RNA). In the complex, the RNA adopts a novel triangular fold on the hexameric surface of HutP, without any base-pairing, and binds to the protein mostly by specific protein-base interactions. The structure explains how the HutP and RNA interactions are regulated critically by the l-histidine and Mg2+ ion through the structural rearrangement. To gain insights into these structural rearrangements, we solved two additional crystal structures (uncomplexed HutP and HutP-L-histidine-Mg2+) that revealed the intermediate structures of HutP (before forming an active structure) and the importance of the Mg2+ ion interactions in the complexes.

Structural basis of HutP-mediated anti-termination and roles of the Mg2+ ion and L-histidine ligand.,Kumarevel T, Mizuno H, Kumar PK Nature. 2005 Mar 10;434(7030):183-91. PMID:15758992^[1]
