Node Color
colored nodes:
query proteins and first shell of interactors

To a lesser extent, can also reduce 5-keto- D-gluconate and oxidize D-gluconate and 1,2-propanediol. Together with KduI, seems to play a role in the catabolism of hexuronates under osmotic stress conditions, substituting for the regular hexuronate degrading enzymes UxaABC and UxuAB whose expression is repressed in these condition [...] (253 aa)

Plays a role in the catabolism of hexuronates under osmotic stress conditions, likely substituting for the regular hexuronate degrading enzyme UxaC whose expression is repressed in these conditions ; Belongs to the KduI family. (278 aa)
higAAntitoxinof the HigB-HigA toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. Functions as an mRNA interferase antitoxin; overexpression prevents HigB-mediated cessation of cell growth and inhibition of cell proliferation. (138 aa)
higBmRNA interferase toxin of the HigB-HigA toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. A probable translation-dependent mRNA interferase. Overexpression causes cessation of cell growth and inhibits cell proliferation via inhibition of translation; this blockage is overcome by subsequent expression of antitoxin HigA. Overexpression causes cleavage of a number of mRNAs in a translation-dependent fashion, suggesting this is an mRNA interferase. mRNA interferases play a role in bacterial persistence to antibiotics; overexpression of this protein induces p [...] (104 aa)
