The biochemical mechanism of proline racemase was first put forward in the late sixties by Cardinale and Abeles [6] using the Clostridium sticklandii enzyme, CsPRAC. The catalytic mechanism of proline racemase was late revisited by Buschiazzo, Goytia and collaborators that, in 2006, resolved the structure of the parasite TcPRAC co-crystallyzed with its known competitive inhibitor - pyrrole ...
Furthermore, proline is rarely found in α and β structures as it would reduce the stability of such structures, because its side chain α-nitrogen can only form one nitrogen bond. Additionally, proline is the only amino acid that does not form a red-purple colour when developed by spraying with ninhydrin for uses in chromatography. Proline ...
Comer Joseph Cottrell Jr. (December 7, 1931 – October 3, 2014) was an American entrepreneur most notable for founding Pro-Line Corp., a business that created the Curly Kit, which brought the Jheri curl hairstyle to the masses and made it easy to achieve at home.
Arginine and proline metabolism is one of the central pathways for the biosynthesis of the amino acids arginine and proline from glutamate. The pathways linking arginine, glutamate, and proline are bidirectional. Thus, the net utilization or production of these amino acids is highly dependent on cell type and developmental stage.
Proline organocatalysis is the use of proline as an organocatalyst in organic chemistry. This theme is often considered the starting point for the area of organocatalysis, even though early discoveries went unappreciated. [ 1 ]
Risso’s dolphins usually travel in pods of 10 to 30 animals. Marine biologists have captured a rare sight of a giant pod of over 1,500 dolphins leaping and swimming off the California coast ...
The cutter Active and a U.S. Customs and Border Protection (CBP) Air and Marine Operations boat crew launched boarding teams to assess the situation. During the investigation, the Coast Guard ...
Four days after he won his third consecutive U.S. figure skating title, Ilia Malinin normally would have put in four to six hours on the ice back at his home rink in Reston, Virginia.
