[https://www.uniprot.org/uniprot/DPRE1_MYCS2 DPRE1_MYCS2] Component of the DprE1-DprE2 complex that catalyzes the 2-step epimerization of decaprenyl-phospho-ribose (DPR) to decaprenyl-phospho-arabinose (DPA), a key precursor that serves as the arabinose donor required for the synthesis of cell-wall arabinans (PubMed:22188377). DprE1 catalyzes the first step of epimerization, namely FAD-dependent oxidation of the C2' hydroxyl of DPR to yield the keto intermediate decaprenyl-phospho-2'-keto-D-arabinose (DPX) (PubMed:22188377). The intermediate DPX is then transferred to DprE2 subunit of the epimerase complex, most probably through a 'substrate channel' at the interface of DprE1-DprE2 complex (By similarity). Can also use farnesyl-phosphoryl-beta-D-ribofuranose (FPR) as substrate in vitro (PubMed:22188377, PubMed:22956199). Appears to be essential for the growth of M.smegmatis (PubMed:21346818).[UniProtKB:P9WJF1]<ref>PMID:21346818</ref> <ref>PMID:22188377</ref> <ref>PMID:22956199</ref>
