    Ecosystem Services of Headwater Catchments (2017)
    Cham : Springer
    Details Availability
    Keywords: Earth sciences ; Hydrology ; Natural disasters ; Environmental sciences ; Regional planning ; Urban planning ; Climate change ; Pollution ; Earth Sciences
    Description / Table of Contents: This book addresses the evaluation of environmental impacts and services identified in headwaters of different eco-zones around the world. It presents 24 papers selected from contributions to recent meetings of the European Forestry Commission Working Party on the Management of Mountain Watersheds, which is coordinated by the FAO (Food and Agriculture Organization of the United Nations). Through its biennial sessions and inter-session activities, the Working Party focuses on the continuous exchange of knowledge and experience between professionals in Europe and other regions of the world confronted with similar issues. The contributions have been updated and peer-reviewed, and the interdisciplinary team of authors includes experts from the fields of geography, hydrology, chemistry, biology, forestry, ecology and socio-economics. The participatory management of headwater catchments in Europe, Africa, America and Asia was the central theme of the articles, which were divided into four sessions: (1) Headwater Environment and Natural Resources, (2) Enhancing Environmental Services in Headwaters, (3) Environmental Services in the Changing World, and (4) New Challenges for Environmental Education and Active Citizenship. The practical applications shown in the book address the multi-resource concept. The book offers a unique and valuable resource for environmentalists, engineers, watershed planners and policymakers alike

    Notes: Abstract The CcmH protein of Escherichia coli is encoded by the last gene of the ccm gene cluster required for cytochrome c maturation. A mutant in which the entire ccmH gene was deleted failed to synthesize both indigenous and foreign c-type cytochromes. However, deletion of the C-terminal hydrophilic domain homologous to CycH of other gram-negative bacteria affected neither the biogenesis of indigenous c-type cytochromes nor that of the Bradyrhizobium japonicum cytochrome c 550. This confirmed that only the N-terminal domain containing a conserved CXXC motif is required in E. coli. PhoA fusion analysis showed that this domain is periplasmic. Site-directed mutagenesis of the cysteines of the CXXC motif revealed that both cysteines are required for cytochrome c maturation during aerobic growth, whereas only the second cysteine is required for cytochrome c maturation during anaerobic growth. The deficiency of the point mutants was complemented when 2-mercapto-ethanesulfonic acid was added to growing cells; other thiol compounds did not stimulate cytochrome c formation in these strains. We propose a model for the reaction sequence in which CcmH keeps the heme binding site of apocytochrome c in a reduced form for subsequent heme ligation.
