preprocessing of model to get the minimal cost iso enzyme and eliminate the OR from GPR's.
getGpr1iso(model, cpx_stoich, MW)object of class modelorg representing the metabolic network.
giving the stoichiometry of complexes: data frame containing at least two columns 'genes','stoich' 1/10/2015 'gene' : delimited string of genes(ordered by geneid(e.g bnumber)), 'stoich': number of subunits of each gene in the same order in 'genes'
MW measurement for gene using readfaa.r, calc_MW or gene annotation [units g/mmol]
return a LIST:
data frame containing the choosen term (complex or isoenzyme)
molecular weight of isoenzyme
matrix of reaction gene with stoichiometry
