Recognition of boxA antiterminator RNA by the E. coli antitermination factors NusB and ribosomal protein S10

Cell, 1993
The boxA sequences of the E. coli ribosomal RNA (rrn) operons are sufficient to cause RNA polymerase to read through Rho-dependent transcriptional terminators. We show that a complex of the transcription antitermination factors NusB and ribosomal protein S10 interacts specifically with boxA RNA.

The reducing component BoxA of benzoyl-coenzyme A epoxidase from Azoarcus evansii is a [4Fe–4S] protein

Biochimica Et Biophysica Acta - Proteins and Proteomics, 2011
BoxA is the reductase component of the benzoyl-coenzyme A (CoA) oxidizing epoxidase enzyme system BoxAB. The enzyme catalyzes the key step of an hitherto unknown aerobic, CoA-dependent pathway of benzoate metabolism, which is the epoxidation of benzoyl-CoA to the non-aromatic 2,3-epoxybenzoyl-CoA.

Role of the spacer boxA of Escherichia coli ribosomal RNA operons in efficient 23 S rRNA synthesis in vivo

Journal of Molecular Biology, 1997
A boxA sequence, known to be important for transcriptional antitermination, is found in both the leader region and in the spacer between the 16 S and 23 S genes of Escherichia coli ribosomal RNA operons. We have shown that a functional leader boxA is important for efficient completion of 16 S rRNA transcription.

High mobility group box-1 (HMGB1) antagonist BoxA suppresses status epilepticus-induced neuroinflammatory responses associated with Toll-like receptor 2/4 down-regulation in rats

Brain Research, 2019
It has been generally accepted that inflammatory responses induced by status epilepticus (SE) in the brain are associated with microglial activation. One important regulator of microglial activation is high mobility group box-1 (HMGB1) protein. HMGB1 exerts its influence on microglia via various pathways including Toll-like receptor (TLR) subtypes 2 ...
