Abstract / Bemerkung
The production of the acidic exopolysaccharide succinoglycan (EPS I) by Rhizobium meliloti exoP* mutants expressing an ExoP protein lacking its C-terminal cytoplasmic domain and by mutants characterized by specific amino acid substitutions in the proline-rich motif (RX(4)PX(2)PX(4)SPKX(9)IXGXMXGXG) located from positions 443 to 476 of the ExoP protein was analyzed. The absence of the (I-terminal cytoplasmic ExoP domain (positions 484 to 786) and the substitution of both arginine(443) by isoleucine(443) and proline(457) by serine(457) within the proline-rich motif resulted in enhanced production of low-molecular-weight (LMW) EPS I at the expense of high-molecular-weight (HMW) EPS I. The ratios of HMW to LMW EPS I of the wild type and mutant strains increased with osmolarity.
