I am looking for a database which I can use to programmatically mark the taxa in my project as either Gram +ve or Gram -ve. It looks like the NCBI used to maintain a file (lproks_0.txt) with this information but they no longer do. If anyone has a resource that I could use for this purpose I would appreciate the help.

Gram Staining is procedure of identifying bacteria in General Laboratory uses. The Gram Stain Kit (Modified Brown & Brenn) is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria.
