Studies have been conducted on the ground-state and excited-state solvolyses of the isomeric 7,8-dichloro derivatives of benzonaphthobicyclo(2.2.2)octadiene and benzoveratrobicyclo(2.2.2)octadiene. The silver ion assisted ground-state reactions proce

E. coli ribonucleotide reductase (RNR) catalyzes the conversion of nucleotides to deoxynucleotides, a process that requires long-range radical transfer over 35 A from a tyrosyl radical (Y(122)*) within the beta2 subunit to a cysteine residue (C(439))

The photocycle of bacterial photosynthetic reaction centers (RCs) involves electron transfer between two quinone molecules, QA and QB. The semiquinone biradical QA-•QB-• forms an intermediate state in this process. We trapped the biradical at low

The rate of electron transfer from BPh{sup {sm bullet}{minus}} to Q{sub A} (k{sub 1}) was determined at 14, 35, 113, and 298 K in reaction center protein from Rhodobacter sphaeroides R-26 in which the native Q{sub A}, UQ{sub 10}, was removed and acti
