The two E1‐subunits of the BCKDH complex, BCKDHE1‐α and BCKDHE1‐β, are of significantly higher abundance in GDM, but evidence for an increased oxidation of BCAAs in GDM is patchy, since the mitochondria‐located branched chain amino transferase (AT1G10060) located upstream of BCKDH was not detected, nor does the E2‐subunit of the complex (AT3G06850) show any differential abundance. Here, PPM1K is linked to gestational diabetes.
