I want to extract only these information from the file "PPI3_SYNY3 " , "Putative thylakoid lumen peptidyl-prolyl cis-trans isomerase sll0408" and "Sequence analysis of the genome of the unicellular cyanobacterium Synechocystis sp. strain PCC6803. II. Sequence determination of the entire genome and assignment of potential protein-coding regions" Here is my code where i am only able to extract the locus id from the file please help me here

 
open(GENBANK, "/Users/ale/Desktop/seq.gp.txt") or die; 

# Opening file results.txt in write mode with the help of ">" operator
+.
    open (FH, ">", "results.txt"); 

my $content = join("", <GENBANK>); 

close(GENBANK);
$content =~ /LOCUS\s+([A-Z0-9_]+)/; 
my $locus = $1;
$content =~ /DEFINITION\s+(\w+\W+);
my $acids = $1 ;

$content =~ /TITLE([a-z0-9+\s]+)/; 

my $aminoAcids = uc($1);
print(FH "$locus\n$acids\n$aminoAcids\n");
