Phosphoketolase pathway
WebSeveral bacterial species and filamentous fungi utilize the phosphoketolase pathway (PHK) for glucose dissimilation as an alternative to the Embden-Meyerhof-Parnas pathway. In … WebDec 1, 2015 · Phosphoketolase pathway engineering Increasing flux through the Pkt pathway can be an effective tool for metabolic engineering (Figure 1). Recent metabolic engineering efforts have shown that this pathway can be used with both pentose and hexose sugars to improve the yields of target molecules (Table 1 ).
