Decreased enzyme activity by about 30% compared to wild-type with L-serine phosphate. No effect on enzyme activity with L-threonine phosphate.
Increased enzyme activity with of L-threonine phosphate and a decreased activity with L-serine phosphate. Exhibits similar activity rates with both substrates.
Loss of enzyme activity with L-serine phosphate and with L-threonine phosphate. No effect in pyridoxal phosphate (PLP)-binding.
No effect on enzyme activity with L-serine phosphate or with L-threonine phosphate.
Significantly decreased enzyme activity. No effect in pyridoxal phosphate (PLP)-binding.
