Chemical Information
FooDB Name6-Hydroxyhexanoic acid
Description6-Hydroxyhexanoate was identified as the immediate product of hexanoate w-hydroxylation by whole cells and was further oxidized into adipic acid and an unexpected metabolite identified as 2-tetrahydrofuranacetic acid. This same metabolite, together with adipic acid, was also detected when similarly induced cells were incubated with hexanoate or 1,6-hexanediol, but not with 6-oxohexanoate (adipic semialdehyde).Cells grown on hexanoate and incubated with 6-hydroxyhexanoate were also found to accumulate 2-tetrahydrofuranacetic acid, which was not further degraded. Utilization of 6-hydroxyhexanoate for growth was restricted to those organisms also able to utilize adipate. Similar observations were made with 1,6-hexanediol serving as the carbon source and cells obtained from one organism,Pseudomonas aeruginosa PAO, grown either on 1,6-hexanediol or 6-hydroxyhexanoate,were found to be well induced for both 6-oxohexanoate and adipate oxidation. The results indicate that 6-hydroxyhexanoate and 1,6-hexanediol are susceptible to both 1B- and w-oxidative attack; however, the former pathway appears to be of no physiological significance since it generates 2-tetrahydrofuranacetic acid as a nonmetabolizable intermediate, making w-oxidation via adipate the exclusive pathway for degradation.
