Open Water Test Series With Six-Bladed Propeller Models

The structure of Rauvolfia serpentina strictosidine synthase is a novel six-bladed beta-propeller fold in plant proteins.

The enzyme strictosidine synthase (STR1) from the Indian medicinal plant Rauvolfia serpentina is of primary importance for the biosynthetic pathway of the indole alkaloid ajmaline. Moreover, STR1 initiates all biosynthetic pathways leading to the entire monoterpenoid indole alkaloid family representing an enormous structural variety of approximately 2000 compounds in higher plants. The crystal ...

Numerical simulation of turbulent flow around the dtmb4119 propeller in open water conditions

In this study, ANSYS-FLUENT packages are employed to simulate the turbulent flow around DTMB4119 propeller in open water conditions. In order to form a mesh, the multiple reference frame (MRF) methodology is used. The results are compared with the experimental results and a good conformity is obtained, which endorses numerical simulation. Furthermore, the  turbulence model is used, which is sup...

The Flow Field of an Infinitely Bladed Propeller with Radially Non-uniform Loading

The flow field of an infinitely bladed propeller of disk loading proportional to (r/R) • (l-r/R) in an incompressible, inviscid fluid is expressed in terms of a series of Legendre functions. Numerical calculations have been carried out for the case n = 5« The radial velocity at r = R, and the shape of the stream surface passing through the periphery of the propeller disk are determined and comp...

Correction: The Carboxy-Terminal Domain of Erb1 Is a Seven-Bladed ß-Propeller that Binds RNA

The Carboxy-Terminal Domain of Erb1 Is a Seven-Bladed ß-Propeller that Binds RNA

Erb1 (Eukaryotic Ribosome Biogenesis 1) protein is essential for the maturation of the ribosomal 60S subunit. Functional studies in yeast and mammalian cells showed that altogether with Nop7 and Ytm1 it forms a stable subcomplex called PeBoW that is crucial for a correct rRNA processing. The exact function of the protein within the process remains unknown. The N-terminal region of the protein i...
