Two disulphide bridges are present in juvenile hormone binding protein from Galleria mellonella.

چکیده
The hemolymph juvenile hormone binding protein (JHBP) from Galleria mellonella contains two disulphide bridges/molecule and no free Cys residues. An alignment of primary structures of other Lepidopteran JHBPs indicates that Cys residues, equivalent to Cys10,17,151,195 in G. mellonella JHBP, maybe involved in -S-S- bridge formation.

The structure of the juvenile hormone binding protein gene from Galleria mellonella.
Juvenile hormone (JH) and ecdysone are the key hormones controlling insect growth and development. The juvenile hormone binding protein (JHBP) is the first member in the array of proteins participating in JH signal transmission. In the present report a whole jhbp gene sequence (9790 bp) is described. The jhbp gene contains four introns (A-D). All the introns have common flanking sequences: GT a...
متن کاملIdentification of specific interaction of juvenile hormone binding protein with isocitrate dehydrogenase.
Juvenile hormone (JH) is essential for multiple physiological processes: it controls larval development, metamorphosis and adult reproduction. In insect hemolymph more than 99 % of JH is bound to juvenile hormone binding protein (JHBP), which protects JH from degradation by nonspecific hydrolases and serves as a carrier to supply the hormone to the target tissues. In Galleria mellonella hemolym...
متن کاملThe Photorhabdus Pir toxins are similar to a developmentally regulated insect protein but show no juvenile hormone esterase activity.
The genome of the insect pathogen Photorhabdus luminescens strain TT01 contains numerous genes predicting toxins and proteases. Within the P. luminescens TT01 genome, the products of two loci, plu 4093-plu 4092 and plu 4437-plu 4436, show oral insecticidal activity against both moth and mosquito larvae. The proteins encoded by these loci, here termed 'Photorhabdus insect related' (Pir) proteins...
متن کاملبررسی اختلالات رشدی و بازدارندگی رشد تنظیم کننده‌های پایریپروکسی‌فن و دیفلوبنزورون در شرایط حرارتی مختلف روی شب‌پره موم‌خوار بزرگ(. Galleria mellonella L)
In this study diflubenzuron as a chitin synthesis inhibitor with a dosage of 25 mg A.I/L, and Pyriproxyfen as a juvenile hormone analogue with a dosage of 0.4 mgA.I/L were incorporated in the wax diets of young and last instar larvae of greater wax moth and reared at different temperatures (25, 30, 35°C). Results showed that these compounds in comparison with control increased larval mortality....
متن کاملPre-exposure to yeast protects larvae of Galleria mellonella from a subsequent lethal infection by Candida albicans and is mediated by the increased expression of antimicrobial peptides.
Pre-exposure of the larvae of Galleria mellonella to Candida albicans or Saccharomyces cerevisiae protects against a subsequent infection with 10(6) C. albicans cells. This protection can also be induced by exposing larvae to glucan or laminarin prior to the administration of the potentially lethal inoculum. Analysis of the genes coding for galiomicin, a defensin in G. mellonella, a cysteine-ri...
