The short-lived (<1 ps) initial intermediate state P(+)B(L)(-) in the photoinduced charge separation process of the bacterial photosynthetic reaction center has been trapped in two D(LL)-based Rhodobacter capsulatus mutants that have Tyr at position M208 and lack the bacteriopheophytin electron acceptor H(L). Transient state P(+)B(L)(-) is characterized by(More)
A novel chromophore composition of the bacterial photosynthetic reaction center (RC) has been discovered: RCs lacking the L-side monomeric bacteriochlorophyll chromophore result from mutation of the native isoleucine at M204 to glutamine in Rhodobacter capsulatus . This conclusion is obtained from 77 K UV-vis spectroscopy and pigment extractions of the(More)
Slow, ∼50 ps, P* → P(+)HA(-) electron transfer is observed in Rhodobacter capsulatus reaction centers (RCs) bearing the native Tyr residue at M208 and the single amino acid change of isoleucine at M204 to glutamic acid. The P* decay kinetics are unusually homogeneous (single exponential) at room temperature. Comparative solid-state NMR of [4'-(13)C]Tyr(More)
Services delivered from satellites in the near-Earth space environment are under threat from orbiting space debris from over 50 years of space operations. Computational modelling studies have shown that even under optimistic mitigation scenarios remediation is necessary to curb the growth. In fact, certain regions of the low-Earth orbit are already(More)
The multi-million-dollar Australian Space Research Program (ASRP) Project – " Platform Technologies for Space Atmosphere and Climate " was awarded to a consortium led by RMIT University in 2010. This benchmark geospatial research forms an important part of the Australian Government's recent space-related initiatives to support national strategic, economic(More)
