Target Pathogen

Overview

Basic information about this protein and its source genome.

Accession: PA3899
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA3899
Status: annotated
Amino acids: 169
Structure source: AlphaFold

GO

GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). GO:0016987 Sigma factors act as the promoter specificity subunit of eubacterial and plant plastid multisubunit RNA polymerases, whose core subunit composition is often described as alpha(2)-beta-beta-prime. Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, the sigma factor binds specifically to promoter elements. The sigma subunit is released once elongation begins. GO:0006352 The initial step of transcription, consisting of the assembly of the RNA polymerase preinitiation complex (PIC) at a gene promoter, as well as the formation of the first few bonds of the RNA transcript. Transcription initiation includes abortive initiation events, which occur when the first few nucleotides are repeatedly synthesized and then released, and ends when promoter clearance takes place. GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. GO:0034756 Any process that modulates the frequency, rate or extent of the directed movement of iron ions (Fe) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
