Camphor 93-100 calmodulin 3 Homo sapiens 0-9 23634216-1 2013 P450(cam) (CYP101A1) is a bacterial monooxygenase that is known to catalyze the oxidation of camphor, the first committed step in camphor degradation, with simultaneous reduction of oxygen (O2). Camphor 130-137 calmodulin 3 Homo sapiens 0-9 23634216-2 2013 We report that P450(cam) catalysis is controlled by oxygen levels: at high O2 concentration, P450(cam) catalyzes the known oxidation reaction, whereas at low O2 concentration the enzyme catalyzes the reduction of camphor to borneol. Camphor 213-220 calmodulin 3 Homo sapiens 15-24 23634216-2 2013 We report that P450(cam) catalysis is controlled by oxygen levels: at high O2 concentration, P450(cam) catalyzes the known oxidation reaction, whereas at low O2 concentration the enzyme catalyzes the reduction of camphor to borneol. Camphor 213-220 calmodulin 3 Homo sapiens 93-102 23634216-5 2013 The reduction of camphor and simultaneous oxidation of water are likely catalyzed by the iron-oxo intermediate of P450(cam) , and we present a plausible mechanism that accounts for the 1:1 borneol:H2O2 stoichiometry we observed. Camphor 17-24 calmodulin 3 Homo sapiens 114-123 23634216-6 2013 This reaction has an adaptive value to bacteria that express this camphor catabolism pathway, which requires O2, for two reasons: 1) the borneol and H2O2 mixture generated is toxic to other bacteria and 2) borneol down-regulates the expression of P450(cam) and its electron transfer partners. Camphor 66-73 calmodulin 3 Homo sapiens 247-256 18513977-1 2008 The two-protein complex between putidaredoxin (Pdx) and cytochrome P450(cam) (CYP101) is the catalytically competent species for camphor hydroxylation by CYP101. Camphor 129-136 calmodulin 3 Homo sapiens 56-76 22468842-1 2012 Removal of substrate (+)-camphor from the active site of cytochrome P450(cam) (CYP101A1) results in nuclear magnetic resonance-detected perturbations in multiple regions of the enzyme. Camphor 21-32 calmodulin 3 Homo sapiens 57-77 22258082-2 2012 The determination of the reaction and activation volumes enabled the construction of the first complete volume profile for the reversible binding of camphor to P450(cam). Camphor 149-156 calmodulin 3 Homo sapiens 160-169 22258082-4 2012 Similarly, the activation volume determined for the dissociation of camphor is influenced by the presence of K(+), which reflects changes in the ease of water entering the active site of camphor-bound P450(cam) that depends on the K(+) concentration. Camphor 68-75 calmodulin 3 Homo sapiens 201-210 22258082-4 2012 Similarly, the activation volume determined for the dissociation of camphor is influenced by the presence of K(+), which reflects changes in the ease of water entering the active site of camphor-bound P450(cam) that depends on the K(+) concentration. Camphor 187-194 calmodulin 3 Homo sapiens 201-210 22258082-5 2012 Careful analysis of the components that contribute to the observed volume changes allowed the estimation of the total number of water molecules expelled to the bulk solvent during the binding of camphor to P450(cam) and the subsequent spin transition. Camphor 195-202 calmodulin 3 Homo sapiens 206-215 22258082-6 2012 The results are discussed in reference to other studies reported in the literature that deal with the kinetics and thermodynamics of the binding of camphor to P450(cam) under various reaction conditions. Camphor 148-155 calmodulin 3 Homo sapiens 159-168 22250969-3 2012 We investigated ET reactions between zinc-substituted cytochrome P450(cam) and small organic compounds such as quinones and ferrocene, which are capable of accessing the protein"s hydrophobic channel and binding close to the active site, like its native substrate, camphor. Camphor 265-272 calmodulin 3 Homo sapiens 54-74 21391540-1 2011 Vibrational coherence spectroscopy (VCS) is used to investigate the low-frequency dynamics of camphor-free and camphor-bound cytochrome P450(cam) (CYP 101) and its L358P mutant. Camphor 111-118 calmodulin 3 Homo sapiens 125-145 21391540-4 2011 The very low frequency region <=200 cm(-1), uniquely accessed by open-band VCS measurements, reveals a mode near 103 cm(-1) in P450(cam) when camphor is not present in the distal pocket. Camphor 145-152 calmodulin 3 Homo sapiens 130-139 16943206-1 2006 We have identified a P450(cam) mutation, L244A, that mitigates the affinity for imidazole and substituted imidazoles while maintaining a high affinity for the natural substrate camphor. Camphor 177-184 calmodulin 3 Homo sapiens 21-30 10587448-1 1999 Tris(2,2"-bipyridyl)ruthenium(II) was used as a light-induced artificial electron donor for the transfer of the first electron to cytochrome P-450(cam) bound with (1R)-camphor and camphane substrates, and in the substrate-free form.
