RT   "Molecular and functional analysis of phosphomannomutase (PMM) from
RT   higher plants and genetic evidence for the involvement of PMM in
RT   ascorbic acid biosynthesis in Arabidopsis and Nicotiana benthamiana.";
RL   Plant J. 49:399-413(2007).
CC   -!- FUNCTION: Involved in ascorbic acid biosynthesis and in the
CC       synthesis of the GDP-mannose and dolichol-phosphate-mannose
CC       required for a number of critical mannosyl transfer reactions (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Alpha-D-mannose 1-phosphate = D-mannose 6-
CC       phosphate.
CC   -!- PATHWAY: Nucleotide-sugar biosynthesis; GDP-D-mannose
CC       biosynthesis; alpha-D-mannose 1-phosphate from D-fructose 6-
CC       phosphate: step 2/2.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- SIMILARITY: Belongs to the eukaryotic PMM family.
CC   -!- CAUTION: PubMed:17217471 indicates this sequence as being of
CC       Nicotiana benthamiana origin.
