Functional Analysis of Two Homologous Mouse Selenophosphate Synthetases
selenium selenophosphate selenoprotein selenophosphate synthetase
2009/3/16
Selenophosphate, a key intermediate in selenium metabolism, is synthesized from selenide and ATP by selenophosphate synthetase(SPS). Mammals have two SPS isozymes known as SPS1 and SPS2. Mouse SPS2 co...
In vitro production of a TRH-homologous peptide and His-Pro diketopiperazine by human semen
TRH-like peptide His-Pro diketopiperazine peptide biosynthesis in semen
2009/2/23
Fresh human semen, diluted 1:1 v/v with 0.15 M NaCl- 0.05 M phosphate, pH 7.5, undergoes a 3-fold increase in total thyrotropin-releasing hormone (TRH) immunoreactivity on incubation at 4 C for 8 to...
Human reproductive tissues contain thyrotropin releasing hormone（TRH）and TRH-homologous peptides
thyrotropin releasing hormone human prostate seminal vesicles testis epididymis
2009/2/20
Thyrotropin releasing hormone (TRH) immunoreactive peptides occur in high concentration within rat ventral prostate and human semen. To extend these observations to human reproductive organs, tissue...
Human semen contains thyrotropin releasing hormone（TRH）, a TRH-homologous peptide, and TRH-binding substances
semen TRH vasectomy exclusion ion exchange high pressure chromatography
2009/2/20
High levels of thyrotropin releasing hormone (TRH) and TRH-homologous peptide, with the general structure pGlu=X-Pro-NH2 where X is either Histidine (His) or a neutral amino acid residue, have been ...
Does Seminal Plasma PSP-I/PSP-II Spermadhesin Modulate the Ability of Boar Spermatozoa to Penetrate Homologous Oocytes In Vitro?
Seminal plasma preservation sperm viability IVF pig
2008/12/22
Low concentration (0.15 mg per million of spermatozoa) of seminal plasma–derived PSP-I/PSP-II spermadhesin heterodimer is able to preserve the viability of highly extended boar spermatozoa. Whether ...
