D-alanine+ligase+(K.+pneumoniae)

K. pneumoniae affects mostly middle ages and older men with debilitating diseases (those with weakened immune systems). The bacteria enters the body through the lungs. The bacteria causes pneumonia and bronchitis. The death rate is around 50%, and up to 100% for people with alcoholism and bacteremia.
 * Target (protein/gene name): **D-alanine ligase (K. pneumoniae)
 * NCBI Gene # or RefSeq#: **
 * Protein ID (NP or XP #) or Wolbachia#: **
 * Organism (including strain): **K. pneumoniae
 * Etiologic Risk Group (see link below): **
 * Disease Information (sort of like the Intro to your Mini __Research Write__ up): **


 * Link to Gene Database page (NCBI, EuPath databases -e.g. TryTryp, PlasmoDB, etc - or PATRIC, etc.) **

Typical antibiotics such as penicillin already attack the components of bacterial cell walls. D-alanine ligase catalyzes the dipeptide d-alanyl-d-alanine, which is an essential building block for cell wall synthesis.
