Extracellular alginate lyase was purified from the culture supernatant of Corynebacterium sp. isolated from the sewage of a sea tangle processing factory in order to elucidate the structure-function relationship of alginate lyase. The electrophoretically homogeneous enzyme was shown to have a molecular mass of 27 kDa by sodium dodecyl sulfate(More)

alpha-Secondary isotope effect provides a useful tool for detection of transient 5,6-dihydropyrimidine intermediates which have been indirectly implicated in a number of chemical and enzymic conversions of pyrimidine heterocycles. The method involves the use of kinetic secondary alpha-hydrogen isotope effects which are expected to accompany sp2 to sp3(More)
The aly PG gene, coding for a poly alpha-l-guluronate lyase (PG lyase) of Corynebacterium strain ALY-1, was cloned and sequenced. The gene consists of 768 bp encoding a signal peptide of 32 amino acids and a mature protein of 224 amino acids. Two disulfide bond cross-linkages were found to be formed between Cys-4 and Cys-51 and between Cys-200 and Cys-206(More)
