Nucleotide sequence of the cDNA encoding silk gland elongation factor 1 beta'.
Most of eukaryotic elongation factor 1 (EF-1) consists of four subunits, EF-la, -/S, -0', and -7, as shown in silk gland, wheat germ (1, 2), Artemia salina (3), and Xenopus laevis (4). EF-la catalyzes the binding of aminoacyl-tRNAs to ribosomes concomitant with the hydrolysis of GTP, while EF-1/3/3'7 catalyzes the exchange of GTP for GDP bound to EF-la subsequent to its release from the ribosom...
متن کاملStudies on the Posterior Silk Gland of the Silkworm , Bomb
Cytolytic processes in posterior silk gland cells of the silkworm, Bombyx mori, during metamorphosis from larva to pupa have been studied. During this stage, the wet weight and the amounts of RNA and protein of the gland decrease rapidly and markedly, while the amount of DNA decreases slowly and slightly. The ultrastructural changes observed at the beginning of the prepupal stage consist of the...
متن کاملProteome identification of the silkworm middle silk gland.
To investigate the functional differentiation among the anterior (A), middle (M), and posterior (P) regions of silkworm middle silk gland (MSG), their proteomes were characterized by shotgun LC-MS/MS analysis with a LTQ-Orbitrap mass spectrometer. To get better proteome identification and quantification, triplicate replicates of mass spectrometry analysis were performed for each sample. The mas...
متن کاملTRANSCRIPTION FACTOR Bmsage PLAYS A CRUCIAL ROLE IN SILK GLAND GENERATION IN SILKWORM, Bombyx mori.
Salivary gland secretion is altered in Drosophila embryos with loss of function of the sage gene. Saliva has a reduced volume and an increased electron density according to transmission electron microscopy, resulting in regions of tube dilation and constriction with intermittent tube closure. However, the precise functions of Bmsage in silkworm (Bombyx mori) are unknown, although its sequence h...
متن کاملSTUDIES ON THE POSTERIOR SILK GLAND OF THE SILKWORM BOMBIX MORI IV. Ultracentrifugal Analyses of Native Silk Proteins, Especially Fibroin Extracted from the Middle Silk Gland of the Mature Silkworm
Ultracentrifugal analyses of the native silk proteins extracted from the various parts of the middle silk gland of the mature silkworm have revealed that there exist four components with S°M,, values of 10S, 9-10S, 9S, and 4S in the extract . It is suggested that the fastest 10S component is the native fibroin synthesized in the posterior silk gland and transferred to the middle silk gland to b...
