CC   -!- FUNCTION: Catalyzes the isomerization of 5-deoxy-alpha-D-ribose 1-
CC       phosphate to 5-deoxy-D-ribulose 1-phosphate, as part of a 5-deoxyribose
CC       salvage pathway that recycles this toxic radical SAM enzyme by-product
CC       to mainstream metabolites. {ECO:0000255|HAMAP-Rule:MF_02229}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-deoxy-alpha-D-ribose 1-phosphate = 5-deoxy-D-ribulose 1-
CC         phosphate; Xref=Rhea:RHEA:61296, ChEBI:CHEBI:58749,
CC         ChEBI:CHEBI:144504; Evidence={ECO:0000255|HAMAP-Rule:MF_02229};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:61297;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_02229};
CC   -!- PATHWAY: Carbohydrate degradation. {ECO:0000255|HAMAP-Rule:MF_02229}.
CC   -!- SIMILARITY: Belongs to the EIF-2B alpha/beta/delta subunits family.
CC       DrdI subfamily. {ECO:0000255|HAMAP-Rule:MF_02229}.
