The respiratory proteins of insects

Journal of Insect Physiology, 2007
For a long time, respiratory proteins have been considered unnecessary in most insects because the tracheal system was thought to be sufficient for oxygen supply. Only a few species that survive under hypoxic conditions were known exceptions. However, recently it has become evident that (1) intracellular hemoglobins belong to the standard repertoire of

Odorant-binding proteins in insects

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
This paper reviews the characteristics of pheromone and odorant-binding proteins (OBP) in insects, with particular reference to Lepidoptera. They are small (15 kDa) soluble proteins, very concentrated in the lymph of chemosensory sensilla and belonging to two major classes, pheromone-binding proteins (PBP) and general odorant-binding proteins.

Insect transferrins: Multifunctional proteins

Biochimica et Biophysica Acta (BBA) - General Subjects, 2012
Many studies have been done evaluating transferrin in insects. Genomic analyses indicate that insects could have more than one transferrin. However, the most commonly studied insect transferrin, Tsf1, shows greatest homology to mammalian blood transferrin.Aspects of insect transferrin structure compared to mammalian transferrin and the roles ...

Protein and sustainability – the potential of insects

Journal of Insects as Food and Feed, 2019
In this research it is aimed to outline the role and potential contribution of insects towards food security and sustainability from a multidisciplinary perspective. First, ecological, economic and social aspects of food sustainability and food security are identified by prioritising the environmental impacts associated with food production and ...

Insect Defense Proteins and Peptides

2020
The composition of insect hemolymph can change depending on many factors, e.g. access to nutrients, stress conditions, and current needs of the insect. In this chapter, insect immune-related polypeptides, which can be permanently or occasionally present in the hemolymph, are described.

Thioester-containing proteins and insect immunity

Molecular Immunology, 2004
Here, we discuss the role of thioester-containing proteins in innate immune responses of insects. TEPs are represented by multi-member families both in the fruitfly, Drosophila melanogaster, and in the mosquito, Anopheles gambiae. Phylogenetic analysis of the family suggests that in these two dipteran species evolution of TEPs followed independent ...

Insect antibacterial proteins: Not just for insects and against bacteria

BioEssays, 1991
AbstractIn response to a bacterial infection, insects launch an array of countermeasures. Among these are the antibacterial proteins, which effectively lyse bacteria or are bacteriostatic. These proteins were generally assumed to be restricted to insects, yet recent information has shown some homologous counterparts in verte brates, including humans ...

SEROLOGY OF INSECT PROTEINS: I. PRELIMINARY STUDIES ON THE PROTEINS OF INSECT CUTICLE

Canadian Journal of Zoology, 1962
Precipitin tests on extracts of larval cuticle of the housefly (Musca domestica L.) showed the presence of several antigenic protein components, and variations in the protein composition of cuticle during larval development were also demonstrated. One antigenic component from third-instar larval cuticle possessed phenol–oxidase activity.

The Protein of Insect Cuticle

Nature, 1941
Odier1, Wigglesworth2, Pryor3 and others have demonstrated the presence of protein in the cuticle of various insects. The most modern study is that of Fraenkel and Rudall4 using material from the pre-pupal and pupal stages of the blowfly Sarcophaga falculata. They showed that in the larval stage the cuticle contains a high proportion of a protein which
