Q57471 (TRAM_RHIRD) Reviewed, UniProtKB/Swiss-Prot

Names and origin

Protein names

Recommended name:
Transcriptional repressor traM

Gene names

Name:

traM

Encoded on

Plasmid pTiA6NC

Organism

Rhizobium radiobacter (Agrobacterium tumefaciens) (Agrobacterium radiobacter)

Taxonomic identifier

358 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Rhizobiaceae › Rhizobium/Agrobacterium group › Agrobacterium

Protein attributes

Sequence length	102 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function

Negatively regulates conjugation and the expression of tra genes by antagonizing traR/AAI-dependent activation. TraM may either bind or modify traR or AAI making them unavailable. Alternatively, traM may bind tra promoters preventing traR activation.
