Amino Acid Composition of the Poliovirus Capsid Polypeptides Isolated as Fluorescamine Conjugates

Total fluorometric amino acid analysis using fluorescamine.

A fllwrometric amino acid analyzer using fllmresramine for the assay of the full array of natural amino ac<ids including prolinc on a single column is reported. The proline determination was carried out by specific introduction of a solution of ,\‘chlorosl~ccinimide into the flow system. Single rolumn fluorometric amino acid analysis was curried out in a significantly shorter time and with a se...

Quinone-Amino Acid Conjugates Targeting Leishmania Amino Acid Transporters

The aim of the present study was to investigate the feasibility of targeting Leishmania transporters via appropriately designed chemical probes. Leishmania donovani, the parasite that causes visceral leishmaniasis, is auxotrophic for arginine and lysine and has specific transporters (LdAAP3 and LdAAP7) to import these nutrients. Probes 1-15 were originated by conjugating cytotoxic quinone fragm...

Studies on the Amino Acid Composition and Antioxidant Activities of Collagen Polypeptides from Holothuria nobilis Selenka

Studies on amino acid composition and antioxidant activities of collagen Polypeptides from the Holothuria nobilis Selenka were carried out in this paper. Results revealed that collagen polypeptides mainly contains glycine(Gly), alanine(Ala), glutamate (Glu), proline (Pro) and hydroxyproline (Hyp) with high medicinal values and good tasting. The rate of delicious amino acid, pharmacodynamics ami...

Radiation Damage to Polypeptides and Proteins in the Solid State: Changes in Amino Acid Composition *

Thin layers of synthetic homopolypeptides (poly-ar-Ala, -Arg, -Asn, -Asp, -Glu, -His, -Lys and -Tyr) and proteins (myoglobin, concanavalin A, trypsin-inhibitor) were irradiated under solid state conditions in an electron microscope with 100 keV electrons. Radiolytic changes were investigated by amino acid analysis. The results are discussed in terms of the relative radiosensitivities of the con...
