Protein Circlets as Sex Pilus Subunits
Current Protein & Peptide Science, 2004The largest circular protein structures discovered define a class of transfer proteins acting in bacterial conjugation and type IV secretion. Proteins ranging from 73 to 78 residues with head-to-tail peptide bonds constitute the major subunit of conjugative pili of some type IV secretion systems.

Placental Proteins and Their Subunits as Tumor Markers
Annals of Internal Medicine, 1975Abstract Placental proteins and their unique subunits are not normally detected in the circulation, even with immunoassays sensitive to 1 ng/ml.

Inheritance of glutenin protein subunits of wheat
Theoretical and Applied Genetics, 1981The inheritance of the high-molecular-weight (HMW) glutenin protein subunits in hexaploid wheat has been investigated by using sodium dodecyl sulphate-polyacrylamide gel electrophoresis to examine the segregation of these subunits in 496 test-cross seeds.

Protein dimers are common in catalysis and regulation. Their associations are either homodimers (identical monomers) or heterodimers (nonidentical monomers). The molecular principles of protein dimer interactions are difficult to understand mainly due to the geometrical and chemical characteristics of proteins.

Spinin: the subunit protein of bacterial spinae
Canadian Journal of Microbiology, 1976Bacterial spines (spinae) dissociate in hot sodium dodecyl sulphate to give a single novel subunit protein, spinin (mol. wt. 37 000 daltons). Spinae and spinin are introduced as new names.

IMMUNOCHEMICAL PROPERTIES OF S‐100 PROTEINS AND THEIR SUBUNITS
Journal of Neurochemistry, 1979Abstract— The immunological activities of two populations of bovine S‐100 proteins with anti‐S‐100 serum were studied by complement fixation and rocket immunoelectrophoresis. The reactivities of subunits of these two populations were studied by crossed immunoelectrophoresis and rocket immunoelectrophoresis. Although the two populations conformed in all

Subunit interactions of GTP‐binding proteins
European Journal of Biochemistry, 1992Fluorescence energy transfer [cf. Förster, T. (1948) Ann. Phys. 6, 55–75] was tested for its suitability to study quantitative interactions of subunits of Go with each other and these subunits or trimeric Go with the β1‐adrenoceptor in detergent micelles or after reconstitution into lipid vesicles [according to Feder, D., Im, M.‐J., Klein, H.

G protein subunits in lung cells
Life Sciences, 1994Many hormones and neurotransmitters bind to membrane-bound receptors that are coupled to signal generating enzymes or ion channels via signal transducing GTP-binding proteins termed G proteins. Although receptors and second messengers have been extensively studied in cells of the respiratory system, the G proteins responsible for the coupling of these ...

An investigation of protein subunit and domain interfaces
"Protein Engineering, Design and Selection", 1988Protein structures were collected from the Brookhaven Database of tertiary architectures that displayed oligomeric association (24 molecules) or whose polypeptide folding revealed domains (34 proteins). The subunit and domain interfaces for these proteins were respectively examined from the following aspects: percentage water-accessible surface area ...
