Mutational analysis of the inactivating factors, IF7 and IF17 from Synechocystis sp. PCC 6803: critical role of arginine amino acid residues for glutamine synthetase inactivation
The Synechocystis sp. PCC 6803 glutamine synthetase type I (GS) activity is controlled by a process that involves protein–protein interaction with two inactivating factors (IF7 and IF17). IF7 is a natively unfolded, 65-residue-long protein, homologous to the...
Cysteine homeostasis plays an essential role in plant immunity
Cysteine is the metabolic precursor of essential biomolecules such as vitamins, cofactors,antioxidants and many defense compounds. The last step of cysteine metabolism is catalysed by O-acetylserine(thiol)lyase (OASTL), which incorporates reduced sulfur into...
Highly Enantioselective Hydrogenation of b-Acyloxy and b-Acylamino a,b-Unsaturated Phosphonates Catalyzed by Rhodium Phosphane-Phosphite Complexes
The enantioselective hydrogenation of b-(acyloxy)- and b-(acylamino)vinylphosphonates with rhodium catalysts based on chiral phosphane-phosphite ligands has been studied. In the case of the b-(acyloxy)vinylphosphonates, the reaction also produces an achiral...
Enhancing the expression of starch synthase class IV results in increased levels of both transitory and long-term storage starch
El almidón es el principal compuesto de reserva de las plantas y además tiene un papel esencial en distintos tipos de industrias, por lo que su estudio se muestra muy interesante tanto desde el punto de vista teórico como aplicado. En este trabajo se ha visto que la...
