#SCPH05 I Biotechnology
  1. It speeds up the alignment of multiple sequences through a multistep process.
  2. It first conducts pair wise alignments for each possible pair of sequences using the Needleman–Wunsch global alignment method and records these similarity scores from the pair wise comparisons
  3. The scores can either be percent identity or similarity scores based on a particular substitution matrix.
  4. Its drawback is it slows down the alignment of multiple sequences through a single step process.

Phenyl ammonia lyase (PAL) involved in biosynthesis of phenolic compound in plants. Following are some statements regarding the action of PAL;

a) PAL catalyze conversion of phenyl alanine to p-coumaric acid

b) PAL catalyzes the conversion of phenyl alanine into trans-Cinnamic acid by elimination of an ammonia molecule

c) The activity of PAL is increased by environmental factors, such as low nutrient levels, light, and fungal infection

d) PAL is situated at a branch point between primary and secondary metabolism, so the reaction that it catalyzes is an important regulatory step in the formation of many phenolic compounds
