malfunction
physiological function
malfunction
mutation that is lethal when the cells are exposed to visible light. The photosensitive phenotype appears to be due to the accumulation of the substrate for the reaction catalyzed by the visB (ubiH) gene product; ubiH mutants accumulate small quantities of 2-octaprenyl-6-methoxyphenol and relatively large amounts of 2-octaprenylphenol

2-methoxy-6-(all-trans-octaprenyl)phenol + a reduced electron acceptor + oxygen
6-all-trans-octaprenyl-2-methoxy-1,4-benzoquinol + a reduced electron acceptor + H2O
no direct biochemical evidence for the enzymatic activity. Based on information obtained from studies with ubiquinone-deficient mutants, a pathway is proposed for ubiquinone biosynthesis in Escherichia coli. ubiH mutants accumulate small quantities of 2-octaprenyl-6-methoxyphenol and relatively large amounts of 2-octaprenylphenol
