P26276 Phosphomannomutase/phosphoglucomutase; PMM / PGM; EC 5.4.2.2; EC 5.4.2.8 from Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1) (see 10 papers)
78% identity, 99% coverage: 6:465/465 of query aligns to 4:463/463 of P26276
- R15 (= R17) mutation to A: KM halves, decreases processivity as dissociation of G1,6P intermediate increases 25-fold.
- Y17 (= Y19) binding ; binding
- R20 (= R22) mutation to A: No phosphoglucomutase activity.
- S108 (= S110) binding via phosphate group; modified: Phosphoserine; mutation S->A,V: About 5% activity, still subject to substrate inhibition and requires G1,6P as an activator; phosphorylation occurs at a different site.; mutation to C: KM for G1P unchanged, kcat decreases 24-fold; G1,6P stimulates reaction by 2-3 orders of magnitude. No stable protein phosphorylation detected, altered ligation of metal residue.
- N110 (= N112) mutation to A: KM halves, decreases processivity as dissociation of G1,6P intermediate increases 30-fold.
- D242 (= D244) binding
- D244 (= D246) binding
- D246 (= D248) binding
- R247 (= R249) mutation to A: Small reduction in KM, small increase in dissociation of G1,6P intermediate.
- R262 (= R264) mutation to A: Increases KM 2-fold, decreases kcat 9-fold for G1P. Alters flexibility of the hinge region.
- K285 (= K287) binding
- H308 (= H310) binding ; binding
- E325 (= E327) mutation to A: Reduces KM and Vmax approximately 2-fold.
- EMSGH 325:329 (= EMSGH 327:331) binding ; binding
- H329 (= H331) mutation to A: No phosphoglucomutase activity using G1P as substrate, protein is less easily phosphorylated, no significant change in structure.
- P368 (= P370) mutation to G: Increases KM 2-fold, decreases kcat 6-fold for G1P. Alters flexibility of the hinge region, structure is less compact.
- R421 (= R423) mutation to C: Loss of phosphomannomutase activity, very low phosphoglucomutase activity.
- RASNT 421:425 (= RASNT 423:427) binding ; binding
