Check Digit Verification of cas no

The CAS Registry Mumber 28105-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,0 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28105-69:
(7*2)+(6*8)+(5*1)+(4*0)+(3*5)+(2*6)+(1*9)=103
103 % 10 = 3
So 28105-69-3 is a valid CAS Registry Number.

Phenylalanine ammonia lyase catalyzed synthesis of amino acids by an MIO-cofactor independent pathway

Lovelock, Sarah L.,Lloyd, Richard C.,Turner, Nicholas J.

, p. 4652 - 4656 (2014/05/20)

Phenylalanine ammonia lyases (PALs) belong to a family of 4-methylideneimidazole-5-one (MIO) cofactor dependent enzymes which are responsible for the conversion of L-phenylalanine into trans-cinnamic acid in eukaryotic and prokaryotic organisms. Under conditions of high ammonia concentration, this deamination reaction is reversible and hence there is considerable interest in the development of PALs as biocatalysts for the enantioselective synthesis of non-natural amino acids. Herein the discovery of a previously unobserved competing MIO-independent reaction pathway, which proceeds in a non-stereoselective manner and results in the generation of both L- and D-phenylalanine derivatives, is described. The mechanism of the MIO-independent pathway is explored through isotopic-labeling studies and mutagenesis of key active-site residues. The results obtained are consistent with amino acid deamination occurring by a stepwise E1cB elimination mechanism. All manner of things: A competing MIO-independent (MIO=4-methylideneimidazole-5-one) reaction pathway has been identified for phenylalanine ammonia lyases (PALs), which proceeds in a non-stereoselective manner, resulting in the generation of D-phenylalanine derivatives. The mechanism of D-amino acid formation is explored through isotopic-labeling studies and mutagenesis of key active-site residues.

Chemoenzymatic routes to enantiomerically pure 2-azatyrosine and 2-, 3- and 4-pyridylalanine derivatives

Moussa, Amer,Meffre, Patrick,Martinez, Jean,Rolland, Valerie

, p. 1339 - 1348 (2012/09/07)

Enantiomerically pure 2-, 3- or 4-pyridylalanine (pya) and 2-azatyrosine (azatyr) are known to present various biological activities. After incorporation into appropriate peptide sequences, these heterocyclic non natural α-amino acids could behave as new substrates or inhibitors of elastase from Pseudomonas aeruginosa. This enzyme is known to be involved in nosocomial infections and infections related to the cystic fibrosis disease. New efficient chemoenzymatic preparations of those compounds using α-chymotrypsin (α-CT) are presented. Springer-Verlag 2011.
