Heme O  (PAMDB000278)

Thumb
IUPAC: 3-[(11Z,16Z)-20-(2-carboxyethyl)-15-ethenyl-10-[(4E,8E)-1-hydroxy-5,9,13-trimethyltetradeca-4,8,12-trien-1-yl]-5,9,14,19-tetramethyl-21,23,24,25-tetraaza-22-ferrahexacyclo[9.9.3.1?,??1??,???0????.0?????]pentacosa-1(20),2,4,6(25),7,9,11,13(24),14,16,18-undecaen-4-yl]propanoic acid
CAS: 137397-56-9
Description: HemeOo is a member of the chemical class known as Metalloporphyrins. These are polycyclic compounds containing a porphyrin moiety and a metal atom. Heme O (or haem O) differs from the closely related heme A by having a methyl group at ring position 8 instead of the formyl group. The isoprenoid chain at position 2 is the same. Heme O, found in the bacterium Pseudomonas aeruginosa, functions in a similar manner to heme A in mammalian oxygen reduction. (WikiPedia)

Guanosine diphosphate mannose  (PAMDB000279)

Thumb
IUPAC: {[(2R,3S,4R,5R)-5-(2-amino-6-oxo-6,9-dihydro-1H-purin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}({[hydroxy({[(2R,3S,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy})phosphoryl]oxy})phosphinic acid
CAS: 3123-67-9
Description: GDP-mannose is a nucleoside diphosphate sugar that is important in the production of fucosylated oligosaccharides. GDP-mannose is transformed to GDP-fucose via three enzymatic reactions carried out by two proteins, GDP-mannose 4,6-dehydratase (GMD) and a second enzyme, GDP-keto-6-deoxymannose 3,5-epimerase, 4-reductase. GDP-mannose 4,6-dehydratase (EC 4.2.1.47) catalyzes the chemical reaction: GDP-mannose <--> GDP-4-dehydro-6-deoxy-D-mannose + H2O. The epimerase converts the GDP-4-dehydro-6-deoxy-D-mannose to GDP-fucose. . GDP-mannose is also synthesized from mannose 1-phosphate via the enzyme ATP-mannose-1-phosphate-guanyltransferase and GTP.
