Abstract |
A new enzymatic resolution process was established for the production of L-threo-3-[4-(methylthio)phenylserine] (MTPS), an intermediate for synthesis of antibiotics, florfenicol and thiamphenicol, using the recombinant low-specificity D-threonine aldolase from Arthrobacter sp. DK-38. Chemically synthesized DL-threo-MTPS was efficiently resolved with either the purified enzyme or the intact recombinant Escherichia coli cells overproducing the enzyme. Under the optimized experimental conditions, 100 mM (22.8 g l-1) L-threo-MTPS was obtained from 200 mM (45.5 g l-1) DL-threo-MTPS, with a molar yield of 50% and a 99.6% enantiomeric excess. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 September 2014.
All research outputs
#5,446,629
of 25,373,627 outputs
Outputs from Applied Microbiology and Biotechnology
#1,292
of 8,290 outputs
Outputs of similar age
#5,593
of 36,588 outputs
Outputs of similar age from Applied Microbiology and Biotechnology
#5
of 27 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done well and is in the 75th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 8,290 research outputs from this source. They receive a mean Attention Score of 4.4. This one has gotten more attention than average, scoring higher than 72% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 36,588 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
