Thank you for your interest in the UM-BBD.

- The pathway for pyrene has been added. This pathway was developed 
  by a student in the 2003 Biocatalysis and Biodegradation class, offered 
  completely over the Internet.[upathway-id:'pyr_map']

- The Pathway Prediction System (PPS) biotransformation rules have been 
  added to and updated. There are now 222 rules. The system can now handle
  324 (58%) of the 557 pathway branches from 108 UM-BBD compounds 
  containing C, H, O, N, P, S and/or halides that initiate pathways 
  containing two or more reactions. A list of all rules is available.  
  Reaction pages that exemplify up to three rules now list all of them. 
  For an example, see the reaction: 
  cis-3-Chloroacrylic acid to Malonate semialdehyde.

- In Biochemical Periodic Tables, there is a new entry for Plutonium (Pu) 
  and updated entries for Copper (Cu), Zinc (Zn), Flourine (F), 
  Chlorine (Cl), Bromine (Br), and Iodine (I).

- On the Useful Internet Resources page, a link to the National Safety 
  Council Chemical Backgrounders has been added and the links to the 
  Agricultural Research Service (ARS) Pesticide Properties Database,  
  Thermodynamics of Enzyme-Catalyzed Reactions from the National 
  Institute of Standards and Technology and GenProtEC: E. coli genes 
  and proteins at the Woods Hole Marine Biological Laboratory, have
  been updated.
