(1978) biochim. biophys. acta 536, 298-305), thus completing the primary structure of the hemoglobin component of trout's blood devoid of heterotropic phenomena. comparison of beta chain from trout hb i with the corresponding sequences from human and carp shows differences of 46.6% and 34.7%, respectively; the sequence (almost completed) of the beta c ...19836824687
vertebrate skin type i collagen: comparison of bony fishes with lamprey and calf.1. characterization of type i collagen alpha chains, alpha 1 and alpha 2, in the skin tissues of carp and common mackerel revealed a marked interspecies difference in cnbr-peptide maps of the alpha 2 chains, suggesting the hypervariability during evolution of the alpha 2 chains relative to the alpha 1 chains. 2. when compared with calf type i collagen, lower vertebrate type i collagens derived from these bony fishes as well as from lamprey were found to exhibit a higher degree of structural simi ...19836839718
magnetic and spectral properties of carp carbonmonoxyhemoglobin. competitive effects of chloride ions and inositol hexakisphosphate.we have extended our studies on the magnetic properties of carp carbonmonoxyhemoglobin and the dependence of these properties upon solution variables. using an improved version of the superconducting magnetometer, we have found that the magnetic susceptibility of carp carbonmonoxyhemoglobin is sensitive to both inositol hexakisphosphate and chloride ion. the dependence upon chloride ion concentration is complex. at relatively low concentrations this anion reverses the effect of inositol hexakisp ...19836852007
quaternary structure and spin equilibria in ferric hemoglobins. a room temperature study.the effective magnetic moments for a number of human and carp methemoglobin derivatives were determined in solution at room temperature. the data permit us to confirm the dependence of the spin-state equilibrium of azide methemoglobin on the quarternary state of the hemoglobin and to demonstrate a similar dependence for both human and carp aquomethemoglobin. in addition, the ph dependence of the effective magnetic moment and the soret spectrum of carp azidemethemoglobin are compared.19836852055
ionic mechanisms underlying the responses of off-center bipolar cells in the carp retina. i. studies on responses evoked by light.off-center bipolar cells show hyperpolarizing responses to spot illumination in the receptive field center and depolarization responses to an annulus in the surround. to understand the ionic mechanisms underlying these responses, we examined the current-voltage relationship of these bipolar cells, input resistance changes during their light-evoked responses, and the reversal potentials of these responses. off-center bipolar cells generally showed inward rectification when they were hyperpolarize ...19836854267
ionic mechanisms underlying the responses of off-center bipolar cells in the carp retina. ii. studies on responses evoked by transretinal current stimulation.transretinal current pulses flowing from the receptor side to the vitreous side of the retina cause transient release of transmitter from the photoreceptor terminals, and in off-center bipolar cells they evoke transient depolarizations with a brief (less than 1 ms) synaptic delay. since it is known that the presence of na+ in the external medium is not essential for this type of transmitter release, we used this procedure to examine the role of [na+]o in the generation of light-evoked responses ...19836854268
