UNSPECIFIED. (1996) The marine picoplankter Synechococcus sp WH 7803 exhibits an adaptive response to restricted iron availability. FEMS MICROBIOLOGY ECOLOGY, 21 (2). pp. 69-76. ISSN 0168-6496Full text not available from this repository.
Laboratory cultures of marine Synechococcus sp. WH 7803 were grown under conditions of restricted iron availability. The culture medium was adjusted to restrict iron availability: (i) by adding the iron chelator EDDA; (ii) by omitting iron; and (iii) by omitting both iron and EDTA. An adaptive response was observed to these iron-restricted conditions, including a decrease in cellular phycoerythrin concentration and synthesis of a 36 kDa polypeptide in [S-35]methionine radiolabelled whole cell lysates separated by SDS-PAGE. The polypeptide was synthesized within 48 h of transferring exponential phase cells to the iron-restricted medium. The protein was localized to the cell membranes and not the cytoplasmic fraction.
