phiXYZp
phiXYZp is a protein that was initially identified during a large-scale proteomic screening of the marine bacterium Pseudomonas sp. strain MC12. The gene encoding phiXYZp is located on a 12-kilobase plasmid that also carries several antibiotic resistance determinants. Bioinformatic analysis places the protein in the DUF1234 family of proteins, for which no definitive function has been assigned.
Structural prediction models suggest that phiXYZp adopts a Rossmann-like fold and contains a conserved glycine-rich loop
In vitro assays show that phiXYZp expression correlates with increased tolerance to oxidative stress, suggesting a
Although the precise physiological substrate of phiXYZp in its native host remains uncertain, the protein has
