Topology and phosphorylation of soybean nodulin-26, an intrinsic protein of the peribacteroid membrane
Soybean nodulin-26, a homologue of bovine eye lens major intrinsic protein (MIP-26), is an integral protein of the peribacteroid membrane in symbiotic root nodules. It comprises 271 amino acids with six potential transmembrane domains and lacks an amino-terminal signal sequence. A full-length nodulin-26 cDNA and its various deletion derivatives were transcribed in vitro after linking them to ba...
متن کاملEmerging functions of nodulin-like proteins in non-nodulating plant species.
Plant genes whose expression is induced in legumes by Rhizobium bacteria upon nodulation were initially referred to as nodulins. Several of them play a key role in the establishment of symbiosis. Yet, nodulin-like proteins are also found in non-nodulating plant species such as Arabidopsis, rice, maize or poplar. For instance, 132 are predicted in the Arabidopsis thaliana Col-0 genome. Recent st...
متن کاملRole of porins in intrinsic antibiotic resistance of Pseudomonas cepacia.
The measured outer membrane permeability of Pseudomonas cepacia to the beta-lactam nitrocefin was low: approximately 10 times less than that of Escherichia coli and comparable to that of Pseudomonas aeruginosa. The purified P. cepacia porin demonstrated an average single channel conductance in 1 M KCl of 0.23 nS.
متن کاملHomology modeling of representative subfamilies of Arabidopsis major intrinsic proteins. Classification based on the aromatic/arginine selectivity filter.
Major intrinsic proteins (MIPs) are a family of membrane channels that facilitate the bidirectional transport of water and small uncharged solutes such as glycerol. The 35 full-length members of the MIP family in Arabidopsis are segregated into four structurally homologous subfamilies: plasma membrane intrinsic proteins (PIPs), tonoplast intrinsic proteins (TIPs), nodulin 26-like intrinsic memb...
متن کاملNodulin 26, a nodule-specific symbiosome membrane protein from soybean, is an ion channel.
Nodulin 26 is an integral symbiosome membrane protein of nitrogen-fixing soybean nodules. Nodulin 26 is a member of a family of structurally homologous membrane proteins with diverse transport functions. Thus, it has been proposed to be involved in symbiosome membrane transport. Despite this claim, there has not been any evidence that nodulin 26 has a transport activity. In this study, nodulin ...
