Aminopeptidases of Bacillus subtilis.
Three enzymes with L- and one enzyme with D-aminopeptidase (EC 3.4.11; alpha-aminoacyl peptide hydrolase) activity have been separated from each other and partially purified from Bacillus subtilis 168 W.T., distinguished with respect to their molecular weights and catalytic properties, and studied in relation to the physiology of this bacterium. One L-aminopeptidase, designated aminopeptidase I...
متن کاملDeveloping and Adult Rat Testis
23 Iron is essential for male fertility and disruptions in iron balance lead to impairment of testicular 24 function. The divalent metal transporter DMT1 is a key modulator of transferrin and non-transferrin 25 bound iron homeostasis. As a first step in determining the role of DMT1 in the testis, we have 26 determined the pattern of DMT1 expression in the developing and adult rat testis. Northe...
متن کاملFunctional analysis of the cooled rat testis.
Direct cooling of the testis results in the depletion of most germ cells in vivo. Germ cell-depleted testes are now commonly used to investigate spermatogenic regeneration and can serve as recipients for germ cell transplantation. The present study explored the effects of cooling rat testes on the depletion of endogenous germ cells, spermatogenic regeneration, and Sertoli cell function. Adult r...
متن کاملThyroid Hormone Function in the Rat Testis
Thyroid hormones are emerging regulators of testicular function since Sertoli, germ, and Leydig cells are found to express thyroid hormone receptors (TRs). These testicular cells also express deiodinases, which are capable of converting the pro-hormone T4 to the active thyroid hormone T3, or inactivating T3 or T4 to a non-biologically active form. Furthermore, thyroid hormone transporters are a...
متن کاملProperties of rat brain dipeptidyl aminopeptidases in the presence of detergents.
Rat brain dipeptidyl aminopeptidases I to IV were assayed in the soluble and membrane-bound fractions of rat brain, and the effects of the detergents Triton X-100 and sodium deoxycholate on their activities were studied. Dipeptidyl aminopeptidases I and II were significantly inhibited in the presence of sodium deoxycholate, but were not affected by the presence of Triton X-100. However, dipepti...
