YdcS was purified and characterized as a PHB synthase, however most PHB remains so there must be another synthase (Dai, 2008). E. coli makes a short-chain poly-(R)-3-hydroxybutyrate (cPHB), called cPHB, of about 140 units that is complexed with polyphosphate and makes a membrane channel (Das, 1997; Reusch, 1999). About 5% of all E. coli proteins, e.g. Hns and OmpA, are conjugated with cPHB (Huang, 1996; Reusch, 2002; Xian, 2007). Putative YdcVUTS ABC transport system. YdcS was initially as an expressed protein identified using 2-D gels and mass spectrometry. The first 22 aa of YcdS are predicted to be a type I signal peptide. RpoS regulon.
