Protamines, in the footsteps of linker histone evolution.
It was perhaps a lucky coincidence that the early attempts to establish the chemical composition of the cell nucleus were initially carried out on such diverse biological systems as salmon sperm heads (1) and geese and chicken erythrocytes (2). Examination of sperm and erythrocyte systems, respectively, lead to the protamine and histone concepts (3). We know with certainty that, with the except...
متن کاملThe Unexpected Effect of Sodium Arsenate on the Interaction between Histone H1 and Sodium N-Dodecyl Sulphate
A Study was made on the interaction between histon H1 and sodium n-dodecyl sulphate (SDS) in the presence of sodium arsenate inside a phosphate buffer of pH 6.4, using spectroscopy and equilibrium dialysis at 27 °C. The binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the Wyman binding potential. The binding data hs been analysed...
متن کاملCommon phylogenetic origin of protamine-like (PL) proteins and histone H1: Evidence from bivalve PL genes.
Sperm nuclear basic proteins (SNBPs) can be grouped into three main categories: histone (H) type, protamine (P) type, and protamine-like (PL) type. Protamine-like SNBPs represent the most structurally heterogeneous group, consisting of basic proteins which are rich in both lysine and arginine amino acids. The PL proteins replace most of the histones during spermiogenesis but to a lesser extent ...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
