CHARACTERISTICS AND INTERMEDIATES OF SHORT-TERM C-14-O-2 INCORPORATION DURING RIBOSE OXIDATION BY HYDROGENOMONAS FACILIS.

abstract：:The kinA (spoIIJ) locus contains a single gene which codes for a protein of 69,170 daltons showing strong homology to the transmitter kinases of two component regulatory systems. The purified kinase autophosphorylates in the presence of ATP and mediates the transfer of phosphate to the Spo0A and Spo0F sporulation regu...
