DESCRIPTION

Also known as BPHY_XANC8, bphP. Photoreceptor which exists in two forms that are reversibly interconvertible by light: far-red light (733 nm) converts protein to the red-absorbing (Pr) form, while red light (630 nm) partly converts the protein to the far-red-absorbing (Pfr) form (PubMed:27107635). Regulates virulence of X.campestris pv. campestris on its host plants, perhaps by fine-tuning expression to ambient light levels and/or spatial cues (PubMed:27621284). The Pr form may sense light and partially inhibit virulence; in the dark (Pfr form) biofilm and xanathan production rise and bacteria are more virulent (PubMed:27621284). Strains overexpressing this protein have significantly decreased amounts of extracellular beta-1, 4-endoglucanase, produce less xanthin and have decreased transcription of genes involved in virulence such as endoglucanases, type 2 secretion systems, xanthan production and flagellar-dependent motility (PubMed:27621284). Forms head-to-head homodimers (PubMed:27107635).
