You are a computational biochemist participating in this international effort. Your project is to identify and investigate the function of the unknown human gene, labeled FABP6. Neither the
structure of the protein for which this gene codes, nor its function, is known. The sequence of the gene was submitted to the sequence database GenBank. GenBank is the NIH genetic
sequence database, an annotated collection of all publicly available DNA sequences.
Genetic material provides a wealth of information that can provide insight into
the structure and function of the protein it codes during translation. Numerous
computational methods have been developed to analyze, compare, contrast,
and characterize gene and protein sequences. In this case study, you will use
a Basic Local Alignment Search Tool (BLAST) sequence alignment and
analysis and information obtained from the Protein Data Bank (PDB) to
identify and investigate the sequence of the unknown gene and the resulting
protein it codes.

The Human Genome Project is an international scientific effort with the goals
of determining the sequence of nucleotide base pairs that make up human
DNA and of identifying and mapping all of the genes of the human genome. It
remains the world's largest collaborative biological project. In the USA, the
project launched in 1990 and was declared complete in 2003. Funding came
from the US government through the National Institutes of Health (NIH),
National Science Foundation (NSF), as well as numerous other groups from
around the world.

Part A- Transcription of DNA
The next step in the study of biological systems was to translate the predicted
genes into protein sequences and study the available proteome, the entire set
of proteins produced by an organism. This new area of biochemistry was
named proteomics. Its goal is a large-scale study of proteins, their structure,
and their function. Numerous labs around the world subsequently turned their
efforts to classifying proteins of unknown function by using sequence analysis
and similar methods developed by computational biochemists.

Part G - Disulfide bonds
Based on the sequence alignment, is it possible that one or more disulfide bonds exist in this structure? Select the best option to explain why or why not, including the predicted number of
disulfide bonds.
• View Available Hint(s)
O Yes, the conserved cysteine and methionine residues will form two disulfide bonds.
O No, the residues needed for form a disulfide bond are located too far away from each other in the sequence.
O Yes, there are two conserved cysteines in the sequence that might create one disulfide bond.
O Yes, there are two conserved methionine residues in the sequence that might create one disulfide bond.
O No, functionally important residues needed to form a disulfide bond are not conserved in the alignment.
