In the acidothermophilic archaeon, Thermoplasma acidophilum, the proportion of D-aspartate (D-Asp) to total Asp was as high as 39.7%. Crude extracts of Thermoplasma acidophilum had Asp-specific racemase activity that was pyridoxal 5~-phosphate (PLP)-dependent. The relative insensitivity to a SH-modifying reagent distinguished this activity from those of the PLP-independent Asp racemases found in other hyperthermophilic archaea (Matsumoto, M., et al., J. Bacteriol. 181, 6560-6563 1999). Thus, high levels of d-Asp should be produced by a new type(s) of Asp-specific racemase in Thermoplasma acidophilum, although the function of d-Asp in this archaeon remains unknown. ------>tmu_sno=None ------>sno=3566 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Long Z, Lee JA, Okamoto T, Sekine M, Nimura N, Imai K, Yohda M, Maruyama T, Sumi M, , Kamo N, Yamagishi A, Oshima T, Homma H* ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Occurrence of D-Amino Acids and a pyridoxal 5~-phosphate-dependent aspartate racemase in the acidothermophilic archaeon, Thermoplasma acidophilum. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no=2 ------>patent_SDate=None ------>update_bywho= ------>publish_year=2001 ------>submit_flag= ------>publish_month=None |
