Retention characteristics of ultra-HPLC (UHPLC) hybrid stationary phases (bridged ethyl hybrid (BEH) and BEH Amide) were studied… Expand We have investigated the physiological response of marine planktonic cyanobacteria to UV-A (320–390 nm) irradiation. Here, we… Expand Nitric-oxide synthase (NOS) requires the cofactor, (6R)-5,6,7,8-tetrahydrobiopterin (H4B), for catalytic activity. The crystal… Expand The authors have examined the response to UV-A irradiation of the UV-A-resistant marine cyanobacterium Oscillatoria sp. NKBG… Expand Autoxidation rates of the full-length neuronal nitric oxide synthase (nNOS) were analyzed and found to be composed of three… Expand Binding of (6R)‐5,6,7,8‐tetrahydro‐l‐biopterin (H4B) stabilizes the homodimeric structure of neuronal nitric oxide synthase (nNOS… Expand Nitric oxide synthase (NOS) catalyses the conversion of L-arginine into L-citrulline and nitric oxide. Recently we have developed… Expand Tetrahydrobiopterin is a cofactor in hydroxylation reactions, including phenylalanine 4-monooxygenase, tyrosine 3-monooxygenase… Expand We have isolated a marine planktonic cyanobacterium Oscillatoria sp. NKBG 091600 which is resistant to ultraviolet-A (UV-A… Expand Specific antibodies against l-erythro-biopterin have been prepared in rabbits using the conjugates to bovine serum albumin. The… Expand
