There are 6 potential glycosylation sites and 13 cysteine residues on F48E9 protein,and 6 F48E9 strain specific sites,37F(L),38S(A),60L(P),105S(N),443A(T),571I(V) are found,which are well conserved in other 13 NDV strains.
Orid, Ade and Scul 160 μmol·L -1 inhibited the increase of P value (0 297±0 022, 0 389±0 009 and 0 382±0 013 vs 0 423±0 014 in ferrous cysteine group) Ade 160 μmol·L -1 prevented the decrease of the absorbane induced by ferrous ascorbic acid in liver mitochondria.
IGFBP6 (insulin-like growth factor binding protein 6) and CYR61 (cysteine rich angiogenic inducer 61) are members of the IGFBP superfamily which can combine with IGFs. They regulate growth development and metabolism by regulating the binding capability between IGFs and IGFs receptor.
IGFBP6(insulin-like growth factor binding protein 6)和CYR61(cysteine rich angiogenic inducer 61)是IGFBP超家族的成员,能与胰岛素样生长因子(IGFs)结合,调节IGFs与其受体(IGFR)的结合能力,从而调节机体生长发育和代谢。
A library of 363 glycoconjugates and C-nucleosides synthesized by our earlier reported methods were screened for their effect on isolated filarial glutamate cysteine ligase (GCL) and glutathione reductase (GR).
glutamate cysteine ligase (GCL) and γ-glutamyl transpeptidase (γ-GT) from bovine filarial worms Setaria cervi and their counterparts from mammalian liver to known inhibitors i.e.
The observation of Koshtoyantz that urea has beneficial effect on muscle fatigued by indirect stimulation, has been confirmed. This"defatigue" effect really only represents a removal of conduction block at the neuromuscular junction. On fatigue of the muscle fibres itself urea has no ameliorating effect. To obtain the above mentioned"defatigue" effect of urea requires rather strict experimental conditions; in particular, the Ringer used to soak the muscle and to prepare the urea solution must contain a smal...
Purified succinic dehydrogenase is a metallo-flavin-adenine protein containing non-haematin iron.The flavin-adenine prosthetic group is firmly bound to the protein part of the enzyme and cannot be split from the latter by boiling in weak acid medium.By digesting with trypsin and chymotrypsin,however,the prosthetic group can be liberated in combination with a peptide chain.The product has been purified by a procedure which involves cresol extraction, mercuric sulphate precipitation,decomposition of the latte...
Since it is known that some organo-fluorine compounds such as fluoro pyrimidines, are capable of inhibiting the growth of rat tumor,it will be of interest to synthesize and study fluoro-containing amino-acids for the carcinostatic action. ω-Fluoro-a-amino butyric,-valenic and caproic acids are the only fluoro-containing aliphatic amino-acid recorded in literature.We have synthesized β-fluoro-α-amino-propionic acid by the following sequence of reactions: When 2-phenyl-4-chloromethylene-5-azlactone (Ⅰ) was tr...
